Adult ADHD vs. High-Functioning Anxiety: Why You Can't Focus

I am a Registered Psychotherapist, not a psychologist or psychiatrist. I do not provide formal ADHD diagnoses or prescribe medication. This article is for educational purposes to help you understand your symptoms. If you suspect you have ADHD, I can support you in managing the associated anxiety and burnout, and help guide you toward the right professionals for a formal assessment.

You look successful on paper. You hit your deadlines (mostly), you show up to meetings, and you keep the wheels turning. But inside, you feel like you're constantly scrambling.

You sit down to work, and your brain feels like a browser with 50 tabs open. You lose hours to scrolling or "busy work," only to panic at 4 PM and hyper-focus to get the real work done.

You've probably asked yourself (or Google): "Do I have adult ADHD?"

It's a valid question. But for many high-performing professionals, the answer isn't always ADHD. Often, it's a nervous system on fire—what we often call High-Functioning Anxiety.

The Shared Symptoms

On the surface, unmanaged ADHD and high-functioning anxiety look almost identical. Both can cause:

  • Procrastination: Putting things off until the last minute.
  • Brain Fog: Feeling unable to think clearly or prioritize.
  • Irritability: Snapping at partners or colleagues when interrupted.
  • Restlessness: An inability to just "sit still" and relax.

The Key Difference: The "Why" Behind the Behavior

While the behaviors look the same, the internal driver is usually different. Understanding this distinction is the first step to getting the right support.

1. The Experience of ADHD (Executive Function)

With ADHD, the struggle is often about initiation and regulation. It’s an issue with the brain's executive functions.

2. The Experience of Anxiety (Fear & Safety)

With High-Functioning Anxiety, the struggle is often about perfectionism and fear. Your nervous system perceives the task as a "threat."

The "Burnout" Mimic

There is a third player in this equation: Burnout.

When you have been running on high-octane stress for years (common in law, tech, and finance), your frontal cortex—the part of the brain responsible for focus—starts to go offline. This is a survival mechanism.

Chronic stress can create "acquired ADHD-like symptoms." Your sleep suffers, your memory slips, and your ability to concentrate evaporates. You haven't suddenly "developed" ADHD in your 30s; your battery is just empty.

How Therapy Helps (Without a Diagnosis)

You don't need a label to start feeling better. In fact, waiting for a diagnosis can sometimes delay the relief you need right now.

In therapy, we focus on calming the nervous system first.

If your focus issues are driven by anxiety or burnout, regulating your stress response will often bring your focus back online. We work on:

What if it really is ADHD?

If we reduce the anxiety and the focus issues persist, that gives us clarity. You now have a much clearer path to take to a psychologist or doctor for a formal assessment. And even with an ADHD diagnosis, therapy remains a crucial tool for managing the emotional regulation and "shame spirals" that often come with neurodivergence.

Stop Guessing and Start Healing

Whether it's a wiring issue or a wiring overload, you deserve to feel calm and capable again. You don't have to navigate this alone.
