autism??

[Aloria]

I've been looking into self-diagnosing autism lately. 
It answers a lot of questions about why I've always felt like an alien. But at the same time, I'm hesitant to actually say I'm definitely autistic because I don't know what that would change for me.
like I've gotten along 40 years being the way I am without knowing. 
anyone else here on the spectrum? Any thoughts, advice, tips, on what comes after diagnosis? Is it worth getting an official diagnosis? Especially in current US political climate?
