Honestly, once you find out you're Autistic, the only problem you can have that you didn't have before are people who hate Autistic people treating you badly. Apart from that, things can only really get better. Once you know, you have explanations and solutions to things that caused you problems before. Before I found out, I was treated like a 'bad kid' and punished for my Autistic traits, but now people at least know why I'm doing it. I've also stopped masking, so it takes me longer to get overwhelmed in most situations because I don't have to make eye contact or stop myself from stimming.
