ADHD or Anxiety? Why Racing Thoughts Can Be So Hard to Interpret

There is a particular kind of frustration that comes from knowing you are capable of difficult things while repeatedly getting stuck on ordinary ones.

You can handle a complex presentation, advise a client, manage a team, write a brief, navigate a difficult conversation, and still spend three weeks avoiding a form that would take ten minutes to complete.

Or you may be the person who completes everything, often early, but only because your mind rarely stops checking what might have been missed.

You reread the email. You revisit the decision. You mentally reconstruct the conversation. You prepare for tomorrow while brushing your teeth, again while commuting, and once more when you are supposed to be falling asleep.

At some point, people in both situations often arrive at the same question:

Is this ADHD, anxiety, or both?

It is not an obscure question. CDC researchers estimated that 15.5 million U.S. adults, about 6% of the adult population, had a current ADHD diagnosis in 2023. More than half, 55.9%, said they had first been diagnosed after turning 18. CDC adult ADHD study

Anxiety is even more familiar. The CDC's 2024 data show that 19% of U.S. adults reported having been diagnosed with an anxiety disorder at some point, while 12% regularly experienced feelings of worry, nervousness, or anxiety. CDC adult anxiety data

Those numbers are useful context. They do not tell you why your mind behaves the way it does.

Racing thoughts are especially poor at doing that. They occur in ADHD and anxiety, but they can also show up with OCD, mood disorders, sleep deprivation, trauma, acute stress, medication effects, and other problems. “My brain never shuts off” describes an experience. It does not explain it.

A more useful place to start is with what your attention is responding to.

What Is Your Attention Actually Responding To?

ADHD is routinely described as a problem with attention. That description is technically convenient and practically incomplete.

Adults with ADHD can sometimes concentrate exceptionally well. A difficult intellectual problem, an urgent deadline, an absorbing project, or something genuinely interesting may hold attention for hours. The same person can struggle to begin a routine administrative task that matters just as much.

The inconsistency is part of what makes adult ADHD so confusing.

If you can produce sophisticated work under pressure, it is easy to conclude that the periods when you cannot get started must reflect motivation, discipline, or character.

But attention is not a simple on/off capacity.

For many people with ADHD, novelty, interest, immediacy, external accountability, and urgency make attention easier to organize. Tasks that are repetitive, open-ended, distant, or poorly defined may require much more effort.

Anxiety pulls attention for another reason.

The unanswered email does not capture your attention because it is interesting. It captures your attention because you do not know what it means.

A colleague's slightly unusual tone becomes difficult to ignore. A decision that looked reasonable yesterday becomes questionable today. You have prepared enough for the meeting, but “enough” does not feel like a stable category.

The common denominator is uncertainty.

The anxious mind keeps returning to what might matter because it has not yet secured enough confidence that everything will be okay.

These distinctions are not clean enough to use as a self-diagnostic test. People with ADHD worry. People with anxiety become distracted. What matters is the larger pattern.

Procrastination Is Not One Psychological Problem

Procrastination is probably one of the least helpful symptoms to interpret without context.

Imagine two attorneys avoiding the same type of memo.

One keeps intending to begin. The document is open. Research has been collected. But the task still feels strangely inert. There are several possible starting points, no immediate pressure to choose among them, and attention keeps drifting toward whatever feels more concrete.

Then the deadline becomes close.

Suddenly, the problem changes. The work becomes immediate. Priorities become obvious. Three hours of concentrated writing follow.

The second attorney is also avoiding the memo, but not because the task lacks enough stimulation. Finishing it means allowing someone else to evaluate it.

One more case might strengthen the argument. One more pass might catch an error. Another hour could produce a better opening.

The work stays unfinished partly because unfinished work has not yet failed.

From a distance, both people “procrastinate.”

That label conceals almost everything clinically interesting about what is happening.

In the first case, breaking the assignment into smaller, concrete steps may genuinely reduce the friction.

In the second, the person may simply perfect the smaller steps.

This is one reason advice that seems obvious can feel useless. It may be aimed at the visible behavior rather than the reason the behavior persists.

Why Competence Can Make ADHD and Anxiety Harder to See

Adults who are struggling significantly do not always look disorganized or distressed.

Sometimes the opposite is true.

A person may be exceptionally punctual because being late became intolerable years ago.

Someone may appear organized because every obligation is entered into three systems.

A professional may have an excellent reputation for preparation because showing up less than completely prepared creates enormous anxiety.

A graduate student may consistently produce strong work, but only through sleep deprivation and last-minute intensity.

An executive may manage complex responsibilities extremely well at work and feel mystified by their inability to keep basic household paperwork under control.

These are not diagnostic examples. They illustrate why outcomes alone tell you relatively little.

If somebody never misses a deadline, the useful question may be how they make that happen.

Does the deadline sit quietly in the calendar until it needs attention? Or does it remain mentally active for days?

Does the person have a proportionate reminder system? Or have they built an elaborate infrastructure around the fear that something will disappear if they stop thinking about it?

This distinction matters in Washington, where a certain amount of hyper-responsiveness can look entirely ordinary. Federal work, law, consulting, healthcare, policy, nonprofit leadership, and other high-accountability roles often reward the same behaviors that can conceal a problem: vigilance, responsiveness, preparation, long hours, and the ability to perform when something becomes urgent.

The question is not simply whether you are getting things done.

A more revealing question is what the current system costs you.

If attention and follow-through feel persistently harder than they should, our page on adult ADHD therapy in Washington, DC goes more deeply into procrastination, time blindness, executive-function problems, emotional overwhelm, and the compensatory effort that can keep ADHD hidden.

If the internal experience is dominated more by worry, anticipation, perfectionism, or the inability to disengage from possible problems, our anxiety therapy page may be the more relevant next read.

The Timeline Matters More Than Most Online Tests Suggest

One of the most useful pieces of information in an adult ADHD evaluation is also one of the least glamorous: your history.

ADHD does not begin at 34 because work became demanding.

NIMH notes that adult ADHD symptoms must have been present before age 12, occur across more than one setting, and cause meaningful impairment. A clinician may look at childhood behavior, school experiences, family recollections, rating scales, current functioning, and alternative explanations. NIMH guide to ADHD in adults

That does not mean a child needed to be disruptive or academically unsuccessful.

Plenty of adults who are diagnosed later did well in school. Some were bright enough to compensate. Some had parents who supplied structure. Some were anxious enough about disappointing people that anxiety functioned as an organizational tool. Some attended schools where every day had a predictable rhythm and every assignment came with a clear deadline.

Adult life removes much of that scaffolding.

Nobody tells you exactly when to begin the project.

A promotion adds vague responsibilities rather than neatly defined assignments.

Parenthood fills the day with interruptions.

Remote work removes environmental cues.

Suddenly, strategies that were adequate at 17 are not adequate at 37.

The important question is not whether your life became harder.

It is whether the harder life exposed an older pattern or created a new one.

If concentration deteriorated only after months of poor sleep, severe anxiety, grief, trauma, or burnout, that deserves attention. If the same themes appear repeatedly across childhood, school, relationships, personal responsibilities, and work, the history tells a different story.

This is why a good evaluation is more useful than an online quiz that asks whether you lose your keys.

When ADHD and Anxiety Become Part of the Same System

The ADHD-versus-anxiety question assumes that the two are competing explanations.

Often they are not.

A 2026 systematic review and meta-analysis of 58 studies involving 18,821 adults found substantially higher anxiety symptom levels among adults with ADHD than adults without ADHD. The researchers also emphasized that results varied with study methods and comparison groups, a useful reminder that overlap is real without being simple. 2026 systematic review of anxiety symptoms in adults with ADHD

In practice, one problem can become the coping strategy for another.

Someone who has repeatedly forgotten obligations may become unusually vigilant about calendars.

Someone who routinely underestimates time may begin arriving absurdly early.

A person who has missed details before may reread everything.

The anxiety is not necessarily irrational in origin. It may have grown around a history of things genuinely going wrong.

The problem is that vigilance has no natural stopping point.

What began as compensation can become a second source of impairment.

The reverse also happens. Chronic anxiety can consume working memory, interfere with sleep, slow decision-making, and make it difficult to concentrate. The person may look distractible because half of their cognitive bandwidth is occupied by threat monitoring.

Eventually the two processes become difficult to separate.

The useful clinical question becomes less “Which diagnosis owns this symptom?” and more “What is currently maintaining the problem?”

What a Careful Assessment Should Look For

A thoughtful assessment should be interested in the places where your story does not fit neatly.

Why can you manage complicated work but not routine administration?

Why does urgency improve your concentration?

What happens when nobody is waiting for the work?

Do attention problems remain when you are relaxed?

Does uncertainty reliably make them worse?

What happens after reassurance?

Do you feel settled, or does your mind produce a slightly different version of the same question?

What happens on vacation?

What happens when a project has no deadline?

How much organization happens automatically, and how much depends on fear, checking, elaborate systems, or external pressure?

Those questions do not diagnose ADHD or anxiety by themselves. They help establish whether the symptoms make sense as part of a larger pattern.

It is also worth resisting the temptation to explain everything through one lens.

Poor sleep can impair attention. So can depression. Trauma can make attention highly sensitive to threat. Burnout can create cognitive fatigue. OCD can produce extraordinary amounts of mental checking that people describe simply as “overthinking.”

Racing thoughts deserve interpretation, not automatic classification.

Treatment Should Follow the Problem, Not Just the Label

The distinction becomes most useful when it changes what you do next.

CBT-informed treatment for adult ADHD often becomes practical quickly. The work may involve making tasks more concrete, externalizing information instead of relying on working memory, improving time estimation, building realistic planning systems, and examining the cycle of avoidance and shame that develops when intentions repeatedly fail to become actions.

A 2025 meta-analysis of 14 randomized controlled trials found that CBT was associated with improvements in core adult ADHD symptoms and executive functioning, with smaller improvements in anxiety or stress and depressive symptoms. 2025 meta-analysis of CBT for adult ADHD

You can read more about that approach on our page about CBT for adult ADHD in Washington, DC.

Anxiety treatment asks somewhat different questions.

What are you trying to prevent?

What would happen if you stopped checking?

What are you hoping another hour of preparation will give you?

How much certainty do you require before acting?

CBT for anxiety may involve reducing avoidance, examining feared predictions, changing reassurance and checking habits, and learning to tolerate decisions that remain imperfectly certain.

That work is less about persuading yourself that nothing bad will happen and more about becoming less dependent on that guarantee.

Our page on CBT for anxiety in Washington, DC explains this approach in more detail.

If repeated doubt is accompanied by intrusive thoughts, reassurance seeking, mental reviewing, or rituals, it is also worth considering whether OCD is part of the picture. OCD therapy in Washington, DC focuses more specifically on that cycle.

When Racing Thoughts Point Beyond ADHD or Anxiety

A sudden or pronounced change from your normal baseline deserves more attention than the phrase “racing thoughts” usually gets online.

Thoughts can speed up when people are severely sleep deprived, under acute stress, using certain substances, adjusting to medications, or experiencing other medical or psychiatric conditions.

Racing thoughts can also occur during manic or hypomanic episodes in bipolar disorder, particularly when they appear alongside meaningful changes in sleep, energy, mood, speech, activity, judgment, or behavior.

The important point is not to add more diagnoses to your search history.

It is to notice whether you are describing a longstanding pattern or a significant change in how you ordinarily function.

Those are different clinical situations.

Finding ADHD or Anxiety Therapy in Washington, DC

The APA's 2024 Work in America survey found that 43% of workers said they typically feel tense or stressed during the workday. APA 2024 Work in America survey

That statistic is worth keeping in mind in a city where professional intensity can easily be mistaken for a personal psychological problem, and where a personal psychological problem can just as easily hide inside a demanding job.

Sometimes the environment is genuinely asking too much.

Sometimes anxiety is making ordinary demands feel dangerous.

Sometimes ADHD makes a poorly structured environment particularly difficult to navigate.

Often several of those things are true at once.

If work itself has become difficult to switch off, our page on work anxiety therapy in Washington, DC may help clarify that part of the picture.

If the larger issue is depletion, emotional exhaustion, or the feeling that your current way of functioning has become unsustainable, see our page on burnout therapy in Washington, DC.

Therapy becomes reasonable before everything falls apart.

A person can be performing well and still be paying too much for that performance in sleep, relationships, mental space, or the ability to have a life that is not organized around work.

Frequently Asked Questions

Can anxiety actually look like ADHD?

Yes. Anxiety can interfere with concentration, working memory, decision-making, sleep, and task completion. Someone who is mentally monitoring risk or replaying a concern may appear distractible because a large share of their attention is already occupied.

The timeline helps. ADHD reflects a persistent developmental pattern. Anxiety-related concentration problems may vary much more with stress, uncertainty, evaluation, relationships, or perceived threat.

Can ADHD lead to anxiety?

It can contribute to it.

Repeated experiences of forgetting, running late, losing track of deadlines, or failing to follow through can make vigilance feel necessary. Someone may compensate by checking more, preparing more, or keeping responsibilities continuously active in their mind.

Eventually the coping strategy can become exhausting in its own right.

Is overthinking ADHD or anxiety?

“Overthinking” is too broad to be diagnostically useful.

Sometimes it describes rapidly branching thought. One idea prompts another and attention keeps moving.

Sometimes it means returning to the same unresolved question repeatedly.

Both can happen in ADHD. Both can happen in anxiety. The content, trigger, history, and purpose of the thinking matter more than the label “overthinking.”

Why can I concentrate for hours if I supposedly have ADHD?

Because the ability to concentrate is not the same thing as the ability to regulate concentration.

Interest, novelty, urgency, immediate consequences, and challenge can make sustained attention much easier. Routine tasks with delayed rewards may be considerably harder.

The clinically relevant question is less “Can you focus?” and more “How reliably can you direct and shift your attention when you need to?”

How can I tell whether procrastination is anxiety or ADHD?

Look at what seems to make the task difficult to approach.

ADHD-related procrastination may involve trouble activating, prioritizing, estimating time, or turning an abstract project into a concrete first step.

Anxiety-related procrastination may protect you from evaluation, uncertainty, failure, or the discomfort of making an imperfect decision.

They also commonly interact. ADHD creates delay, the delay creates anxiety, and anxiety makes the task even harder to approach.

Could it actually be burnout rather than ADHD?

Possibly.

Chronic stress and burnout can cause concentration problems, forgetfulness, indecision, sleep disruption, irritability, and reduced cognitive stamina. If the difficulties emerged primarily during a prolonged period of overwork or exhaustion, that context matters.

A longstanding history of attention, organization, and time-management problems points in a different direction.

What if I have ADHD and anxiety?

Then treatment should account for both.

Simply improving organization may not resolve chronic worry. Working only on worry may not solve executive-function difficulties.

The useful question is how they interact. Perhaps disorganization creates anxiety. Anxiety increases avoidance. Avoidance creates more unfinished work. The unfinished work creates urgency, and urgency becomes the only reliable way to focus.

That cycle is more informative than deciding which diagnosis deserves top billing.

Do I need to know what I have before I contact a therapist?

No.

You can start with what you know from experience.

Maybe work is taking twice as long as it should. Maybe your mind keeps returning to the same concerns. Maybe organization is technically working but requires constant vigilance. Maybe you alternate between intense productivity and complete avoidance.

Those are useful starting points.
