I didn't think my impairments were significant, to the point that it took me 20 years to go talk to a psych about it. My siblings were already diagnosed and nothing like me (in terms of symptoms) so I thought I was 'fine'.

After talking to a psych I got diagnosed ADHD. After starting medication, and increasing multiple times, it was discovered my ADHD is on the severe end.

I've finally found the dose which works for me, which was over the recommended prescribed amount (as directed by my psych) and it's absolutely changed my life. It doesn't remove the impairments, but has reduced severity enough that I can actually deal with them now. My mental health has improved so fucking much, I feel like I have agency now

I strongly recommend you discuss it with a psych, if even to get a negative diagnosis.

> ergo if you don’t think they are, you don’t have ADHD

It's quite possible to be significantly impaired by something, and not realise that you are. This sounds like saying, "if you don't think you're an alcoholic, you aren't".

Or if others don't think they are...
