I have trouble accepting that I'm autistic

Hello :)

Lately I've been having trouble accepting myself? Basically, I'm autistic, and throughout my whole life, my family and my enviroment have brushed it off as something not really that important because I'm """high functioning""". However, I notice how it affects my relationships and interactions with other people on the daily, whether it's by not knwoing how to answer, taking time to process the information that has been said to me or the fact that my emotions do not match my facial expressions. Sure, I know that being autistic may have some advantages, like for example, I'm doing well in high school and with more ease than the usual teenager, but I can't socialize well, which makes me feel... isolated? And it's not easy going through the 6 hours all by myself.

I've always tried to seem normal because "my level of autism is very low", but I guess I can't ignore it no longer.

If I could be given tips on how to help myself with this so I can begin to assimilate that I do not have autism,but instead that I am autistic, I would be really grateful.
