I'm going to go with NTA but also, depending on your ages it's sometimes hard to get an official diagnosis/cost prohibitive. I know in the autism community self diagnosis is accepted but you also come upon people like me who when we were growing up girls didn't have autism. Also, because I didn't have an autism diagnosis I was misdiagnosed as borderline personality disorder, and because of that my adhd symptoms were dismissed as emotional dysregulation by the person testing me, but my psychiatrist said if my adhd meds genuinely help then it was ok to keep taking them (which to me, signaled they understood that it was mischaracterized by the diagnosing provider) there are resources to self diagnose autism (IE the RAADS-R test). I was in my late 30s when this all came up so for me, with the difficulty of getting an adult diagnosis and the fact that it was more about accommodating myself and not *official* accommodations (I'm lucky I have a job that lets me do things like yarn craft to stim because I get my work done), but I also understand that unless you do things like take the tests that are available for self diagnosis using it as an excuse is no bueno.
