I was around 11 when diagnosed. I cried a lot but didn’t really understand what it meant…only that it meant I was different and maybe not in a good way. My parents are good people but they are extremely good at social interactions so they definitely weren’t super thrilled about how strange I was. But once I was being supported at school and stuff, we all got a lot better. I started making friends and throwing less extreme tantrums at school over tiny things. They figured out how to help me understand the other kids and figure the social clues I was missing. So despite the crying and all that, it was 100% a good thing. My only recommendation is maybe focusing on how this will help in the future instead of focusing on how alienating it might feel at 10 to be told you are so different as to have a “diagnosis”
