That sounds awful I'm sorry. Even were told you were that doesn't mean a stigma for your situation, it's all personal.
I've learned to navigate life best I could, have done well enough but not as well as I probably could have. Even if you have it I've never known what any diagnosis could solve. Its sort of a thing ya just gotta go work through in your life is all. Like a dummy weight off the boat you stear against. Don't do much nautical stuff so hope that fits.
I hope you figure out your path.
Also never had anyone think I was autistic but never had many people around to mention otherwise, plus wasn't a big thing when I grew up so now just figured this is me. But I realize I'm not what people would assume as normal once they scratch the surface is all.
