My child’s diagnosis came first.
We’d spent months — years, really — noticing that something about how he experienced the world was different. Not wrong. Not less. But different in ways that the systems around him weren’t built for, and in ways that were costing him enormously.
When the assessment confirmed autism and ADHD, I felt mostly relief. Finally: a framework. Finally: language. Finally: access to support we’d been struggling to navigate without it.
What I wasn’t prepared for was what happened next.
The mirror effect
I’d been reading everything I could find — about his experience, about autism, about ADHD, about what support might look like. And somewhere in that reading, I kept stopping.
Because I recognised it.
Not all of it. But enough. The executive function difficulties I’d explained away as laziness for three decades. The sensory things I’d learned to manage so automatically I’d forgotten they were there. The way social situations were tiring in a way other people didn’t seem to find tiring. The hyperfocus, the black-and-white thinking, the very specific way my brain processed emotional information.
I wasn’t reading about my child. I was reading about myself.
What late diagnosis actually feels like
People who haven’t been through it sometimes imagine late diagnosis as a sudden, clarifying revelation. In some moments it is. But mostly it’s messier than that.
There’s relief — sometimes enormous relief. The sense that something that had always felt slightly wrong finally has an explanation. That you weren’t lazy, or difficult, or too sensitive. You were just wired differently in a world that wasn’t built for you.
But there’s also grief. Grief for the version of yourself that spent decades without that framework. For the support you could have had. For the easier path that might have existed.
And there’s the complicated work of separating who you actually are from the adaptations you made to survive. Which parts of you are genuinely you, and which parts are the mask you built so early you’ve been wearing it ever since?
That work takes time. It doesn’t resolve quickly.
The specific experience of parenting a newly diagnosed child while processing your own diagnosis
This part doesn’t get talked about enough.
You are simultaneously:
- Navigating a system that is complex, underfunded, and often hostile to families like yours
- Advocating fiercely for your child in meetings where you need to be sharp, organised, and credible
- Managing your own neurodivergent brain in exactly the conditions that are hardest for it (emotional stakes, bureaucratic complexity, chronic uncertainty)
- Processing a significant shift in your own identity and history
And you’re often doing all of this without having told anyone. Because telling people means having a conversation you’re not ready to have, in a context where you need to be taken seriously.
It is a lot. It is allowed to be a lot.
Some things that actually helped
Not trying to do it all at once. The diagnosis doesn’t require an immediate response. You can let it settle.
Finding the right community. Not every late-diagnosis space is right for everyone. Some skew younger. Some are heavily focused on identity politics in a way that isn’t always useful when you’re also exhausted. But the right one — the place where people just understand, without explanation — is worth looking for.
Separating your journey from your child’s. Your diagnosis is yours to process in your own time. Your child’s support needs don’t wait — but you’re allowed to have your own experience alongside theirs, even if processing it has to happen in fragments.
Getting your own support. This sounds obvious and is surprisingly hard to prioritise. But if you’re running on empty while advocating for your child, neither of you gets the best of you.
There’s more I want to write about this — about the assessment process as an adult, about what post-diagnosis support actually looks like (and the gap between what it should look like and what’s available), about the experience of being a newly diagnosed parent in SEND-related meetings.
