There was always an inside joke I didn't know about. That's still the best way I can describe what it felt like growing up — like everyone else was tuned to a frequency I was just slightly off, picking up interference, hearing something but not quite the right thing.

I was 36 when I found out the gap I'd felt my whole life had a name. And in Episode 4 of The Weighted Blanket, I talk about all of it — the relief, the low that came afterwards, who I told and who I didn't, and the bits I'm honestly still working through. If you've recently had a late ADHD diagnosis, or you're sitting in that strange in-between place of almost knowing, this one's for you.

Getting diagnosed with ADHD at 36

My diagnosis came through a private assessment. It started with a questionnaire, then a more detailed one that someone who'd known me a long time had to fill in too — my husband did that, and I still think about everything he must have written, all the things he'd watched me carry without either of us having the words for it.

The doctor was brilliant. Compassionate. She asked me a lot about my childhood and the things I'd been through, and I got a bit tearful, because there was a lot to unpick. And at the end she said something I've thought about almost every day since: you're not broken. Your brain just works differently. Now it's about harnessing that.

I cried the whole way home.

The bit nobody warns you about

Here's what I want people to know, because nobody told me. The first feeling was elation — everything I'd ever struggled to explain suddenly made sense, and it felt incredible, empowering even.

And then, a bit later, came something I really wasn't expecting. A significant low. Because once the elation settled, I was left with this question: I've spent 36 years building a whole way of being around a brain I didn't understand, so… now what? What's actually me, and what's the persona I built to fit in? I don't have a neat answer to that yet. I'm not sure there is one. I'm still in it.

Why so many of us were missed

I'm not angry about the years without knowing — mostly I feel a kind of sadness for a younger version of me who was working twice as hard as she needed to and didn't know why. But I do understand why I was missed.

I wasn't the disruptive child. I wasn't the one teachers worried about. I was an introvert who held everything in, and the chaos was completely internal — invisible to anyone looking. And I think that's one of the reasons ADHD in women and girls gets missed so consistently. We're so often the ones sitting quietly and crumbling silently, and the system just isn't built to look for us.

If you were the "good" quiet one too, and you're only working this out now, years later: you weren't lazy, or dramatic, or too much. You were just never looked for.

What's actually changed

Honestly? In my day-to-day, almost nothing — and I think that surprises people. I'm in titration, finding the right dose, and doing some work on the intrusive thoughts. Those things are helping, gradually. But I've still got the same brain. I still get the hyperfocus and the crash, and the days where I can't get going and the guilt sits heavy.

That guilt is the thing I'm really working on. For 36 years I didn't know those days had an explanation — I just thought I was failing. And unlearning that is slower than the diagnosis was, slower than the prescription was. It might be the work of a lifetime.

But I'm in it. And I know more than I did. And knowing, even when it doesn't fix anything, is something.

Listen to Episode 4

If any of this lands for you, come and have a listen — it's one of the more honest ones I've recorded.

And if the hard days leave you sitting in guilt, the free Two-Circle Reset is a five-minute thing I made for exactly those moments: https://the-weighted-blanket.kit.com/5minreset

You don't have to have any of it figured out. You're not broken — you're just working out which parts are you and which parts were armour, and that takes time. Be patient with yourself.

You're not alone. I'll see you in the next one.
