I got diagnosed with autism when I was 5 but struggle to believe I am

I was diagnosed with Aspergers when I was 5, but now that I'm getting older I just feel like the diagnosis was wrong, maybe they thought a couple unique things I did were signs of autism but were incorrect? I'm not sure, I mean, I have like stims, I squeal, throw my hands up, clap,n jump when I'm excited, I clench my jaw or open my mouth wide when I'm uncomfortable, like physically, I tend to not know what to say during conversations like everrr, like even the most simplest of conversations, I have to think hard about how to reply, I CAN make eye contact, thats not a difficult thing, I dunno if I struggle with nonverbal communication, I don't think I do.., I don't have difficulty understanding others emotions, I totally do understand them! I suppose I do have unusual speech patterns, I go from high-pitched to kinda low within seconds, its more like noticing how weird I sound and trying out different pitches, I guess? my voice pitches just randomly change for some reason, I DEFINITELY do not understand sarcasm, unless its super obvious, I'll genuinely believe the sarcastic comment, I definitely do become super focused on a specific activity, to the point if anyone talks to me, I cant hear them. I get SUPER sensitive over unexpected changes, like it could be the smallest thing and i'd be so upset. I do indeed have repetitive movements, I tend to rock myself back and forth for comfort, and like roll my wrists in circles for comfort too. I have really bad sensitivity to textures, foods, fabrics, all that good stuff. But I don't struggle that much with social stuff, and isn't that the main thing? I guess I write well, like when I'm not writing like an intellectual kid, I use a big vocabulary. I just type terribly whenever idc who's gonna see it, yk? js depends who I'm talking to. ANYWAYS sorry, I'm yapping away, I was just curious if anyone else struggled with believing they were autistic? I just feel like an ordinary person, yk. BUT I do have really good writing skills, to the point I was getting offered to be in a YALE program, and a YALE scholarship if I got my schoolwork done :] ANYWHO again, yapping, just reply if you relate?? Pls and ty!
