Hey I'm 17 (as of this edit, January 2024) and I've been diagnosed with ADHD since second grade (American). I was wondering if people with autism and ADHD could tell me a bit about how they knew they had both instead of one or the other because I suspect I might have autism, but I don't want to like, jump to conclusions or anything in case I'm just exaggerating some personality traits and ADHD symptoms.
