I Didn’t Know I Had ADHD Until My 30s. Here’s What That Taught Me.

Fifteen years ago, if you had told me I had ADHD, I would have laughed. Not defensively — just genuinely. I was a psychiatrist. I understood the diagnosis. I knew what it looked like. And it didn’t look like me.

I was wrong, of course. But the more interesting question isn’t why I was wrong. It’s why everyone around me was wrong too — why a lifetime of symptoms went completely unrecognized by my parents, my teachers, my pediatrician, and eventually the colleagues I trained alongside. That question is what shaped my practice.

The Girl Who Talked Too Much

I was constantly being reprimanded for talking in school. This is not a small detail — it was a recurring theme across every grade, every classroom, every teacher’s patience. My high school psychology teacher, of all people, gave me a B in a course I had clearly earned an A in. The stated reason: my disruptive chit-chat. I was eventually asked to leave Hebrew high school because I could not stop talking.

The forgetfulness was just as constant. I lost my house keys, my car keys, library books, homework — routinely and without explanation. I was always behind, always slightly overwhelmed, always anxious about everything I’d forgotten or hadn’t finished. To the people around me, this looked like a quirky, spirited girl who needed to settle down. To me, it just felt like who I was.

Looking back, I can see what was happening clearly. At the time, I couldn’t. None of us could.

“My parents, my teachers, my pediatrician — none of them saw it. And neither did I, until my 30s. That’s not a failure of intelligence. It’s a failure of a diagnostic system that wasn’t built to find me.”

The Anxiety That Masked Everything

Here is the thing about anxiety in a person with undiagnosed ADHD: it can look, from the outside, like conscientiousness. Like effort. Like drive.

My anxiety made me work harder than my peers. The fear of shame, the desperate need to not fall behind, the hypervigilance about what I might have forgotten — all of it produced enough external performance to reassure everyone around me, including myself, that things were fine. My grades were acceptable. My relationships were intact. I was managing.

What no one saw was the internal cost. How much harder I had to work for the same output. How much mental energy went into compensating for a working memory that didn’t function like everyone else’s. How exhausted I was by a brain that was always running at full speed but never quite in the right direction.

Anxiety didn’t protect me from ADHD. It hid ADHD from everyone who might have helped me.

Why Women Get Missed More Than Men

The diagnostic framework for ADHD was constructed largely around boys — specifically, hyperactive boys whose symptoms were impossible to overlook in a classroom. Girls, and later women, tend to present differently. We internalize. We mask. We develop compensatory strategies so effective that they conceal the underlying disorder even from trained clinicians.

The result is a staggering diagnostic gap. Research suggests that only around half of adults with ADHD are ever formally diagnosed. For women, the gap is wider, the delay is longer, and the years between first symptoms and accurate diagnosis are frequently filled with other labels — anxiety disorder, depression, mood dysregulation — that address the surface without touching the cause.

The DSM criteria for ADHD still do not include several of the most characteristic features in women: emotional dysregulation, sleep disturbance, rejection sensitivity, the way symptoms intensify across the menstrual cycle. A checklist that doesn’t ask the right questions will consistently miss the right answers.

The Diagnosis — and What It Reframed

It wasn’t until my 30s that my symptoms became impossible to rationalize. The strategies that had carried me through school and early training were no longer enough. The demands had compounded beyond what compensation could cover. I was finally seen by an ADHD specialist — a clinician who knew what to look for and where to look for it.

The diagnosis reframed almost everything. The chronic procrastination — which I had spent years interpreting as laziness, even knowing the neuroscience said otherwise. The emotional intensity that felt disproportionate to the situation. The impulsive decisions. The way I could lose an hour to something irrelevant while the important thing sat undone, urgent and unavoidable.

None of it was character. All of it was neurology. And once it had a name, it became something I could actually work with.

“A diagnosis didn’t excuse the things that had been hard. It explained them. There’s a significant difference, and that difference matters enormously for how you move forward.”

What It Taught Me as a Clinician

I built this practice with a specific intention: to be the clinician I needed and didn’t have. Someone who knows where ADHD hides in women. Someone who won’t look at a functioning, anxious, high-achieving woman and conclude there’s nothing there.

When a patient tells me she’s been treated for anxiety for eight years and still doesn’t feel right, I don’t hear treatment failure. I hear an incomplete picture. When someone describes doing everything right and still falling behind, I don’t hear lack of effort. I hear a brain working against architecture that hasn’t been properly understood.

My story isn’t unique — it’s common. Millions of adults, a disproportionate number of them women, are living with undiagnosed ADHD right now. Many of them have already been told there’s nothing wrong with them, or that they just need to manage their anxiety better, or that if they just tried harder things would click into place.

They deserve a more precise answer than that. And I know, from the inside, what it means to finally get one.
