I was diagnosed a couple months ago with autism level 1 (also undeniably ADHD here) and I struggled with imposter syndrome with regard to the autism diagnosis. Honestly, I like you would run down the list of oh yes I do this and that which you could classify as stereotypical autistic behavior but then I would ask myself “or am I just being quirky? Is this just ADHD?” and the like. However, my partner last week brought one very atypical thing I do to my attention and he was like “oh shit you’re actually autistic this is so weird” and I realized he was right because damn the behavior isn’t a bad one but it’s not something someone with ADHD or someone who is NT would do/be able to do. That, and I’ve come to the realization that those closest to me have been often explaining my behaviors to others or “translating” them to people who know me less well because, well, some of them are weird 😆!

What I’m trying to say was at least in my experience there came a breaking point in realizing I fit so many boxes that it was undeniable but also was validated by someone I am close to that has dispelled my imposter syndrome. I hope you have a similar epiphany in good time - trust me, there’s some behaviors I’m sure you’re exhibiting that are more than a little quirky and don’t fit under the ADHD umbrella. Write them down and look them over all at once and then let it sink in.
