The first feeling was relief. I thought to myself, "So much makes sense now". And, "it wasn't my fault".
For a few days I felt lighter than I had in years. Everything I'd quietly blamed myself for suddenly had a reason. The unfinished projects. The bursts of brilliant energy followed by the crash. The way ordinary admin took me three times longer than it seemed to take anyone else, even while I was building companies.
Then, about a week later, something else arrived. It didn't announce itself. It showed up as tears in the car, a strange flatness, and a question I couldn't stop asking: what would my life have looked like if someone had noticed sooner?
Nobody had warned me about that part.
Relief comes first. Then something else.
Most of what you read about late diagnosis focuses on the relief, and the relief is real. But it's rarely the whole story.
In one of the earliest studies of adults receiving an ADHD diagnosis, UK researchers described a sequence of emotional responses that ran from relief and elation, through confusion, anger, sadness and grief, and on towards acceptance (Young et al., Journal of Attention Disorders, 2008). A more recent qualitative study of women diagnosed in adulthood found the same pattern: relief and understanding, alongside sadness and anger about the past (Morgan, Advances in Mental Health, 2024).
No two women move through it in the same order, and plenty circle back. The point isn't the sequence. It's that grief belongs in the picture at all, and almost nobody mentions it at the point of diagnosis.
What the grief is actually for
When women describe this to me, the grief usually has a few different targets. Naming them helps, because grief without a name tends to turn into self-criticism.
The younger you. The girl who was called bright but lazy, chatty, dreamy, too much or not trying. She was doing her best with a brain nobody had explained to her.
The effort. Decades of working twice as hard to look half as organised. The over-preparing, the late nights catching up, the energy that went into holding it together and never got spent on anything else.
The "what ifs". The degree you dropped, the job you left, the relationship that strained under things you couldn't explain. It's natural to run the alternative timeline. It's also exhausting.
The story you told about yourself. For a lot of women, the hardest part isn't the past. It's realising that the explanation they'd built for themselves ("I'm just disorganised", "I'm not a details person", "I work best under pressure") was only part of the truth.
None of these are signs you're doing it wrong. They're signs you're taking your own life seriously.
Why it lands harder in your forties and fifties
A diagnosis in midlife arrives with its own timing problem.
For many women, it comes in the middle of perimenopause, when the systems that held for decades have started to slip. I wrote about that in Is it ADHD or perimenopause? The short version is that perimenopause doesn't cause ADHD. For many women, it removes what was hiding it. So you're often grieving the past while your present feels unfamiliar too.
There's also the maths of it all. At 25, a diagnosis feels like a long runway. At 45 or 52, it's tempting to count the years behind you rather than the ones ahead. Add kids, ageing parents and an demanding tech startup or career and there's very little room to sit with any of it.
Grief isn't a step backwards
Here's what I wish someone had told me. Grieving the years before your diagnosis doesn't mean you're stuck in them. It means you're finally seeing them clearly.
Those years weren't wasted. They were full of workarounds, adaptations and sheer determination. Every system you built without knowing why you needed it is proof of resourcefulness. You kept going without the information that would have made it easier. That's not a deficit. That's capability operating without a map.
The grief and the strength come from the same place. You can feel both.
“Grieving the years before your diagnosis doesn’t mean you’re stuck in them. It means you’re finally seeing them clearly.”
Holding grief and building forward at the same time
You don't have to finish grieving before you start building. In my experience, most women do both at once, and that's fine.
A few things that help:
Name it when it shows up. "This is grief" is a very different sentence from "what's wrong with me". The first one is kinder and more accurate.
Don't rush the reframe. Strength-first doesn't mean skipping the hard part. It means not staying there forever.
Write down what you built. List the systems, habits and workarounds that got you this far. You'll need that list later, because some of them are worth keeping.
Start small and practical. One system that fits the brain you have now will do more for you than a complete life overhaul.
Get the right support for the right job. If the grief feels heavy, persistent or tangled up with anxiety or low mood, a therapist or counsellor is the right person to help you process it. Coaching is forward-focused. It works alongside that support, not instead of it.
If you're still wondering whether ADHD is part of your story, that's a valid place to be too. Many women feel some version of this grief before any formal assessment. Why so many women are being diagnosed with ADHD in perimenopause is a good place to start.
What I'd tell the woman in the waiting room
If I could sit next to my 49-year-old self on the day she got her diagnosis, I wouldn't tell her to cheer up or look on the bright side. I'd tell her that both feelings are allowed. The relief and the grief. And that the second one won't last forever, even though it'll feel like it might.
I'd also tell her what I've written about before: a late diagnosis isn't a late start. There's a lot of life ahead, and now she gets to live it with the full picture.
If you're in that place now, diagnosed or wondering, you'll find more about how I support women at this stage on my Women in Midlife coaching page.
