Question, then, if it's not too personal (and apologies if it is): What prompted the autism diagnosis then?
That's not intended to be argumentative or confrontational!

I'm trying to understand something here.
I'm self-diagnosed, and when I first began suspecting that I might be autistic, I had a relatively small number of "Aspie tendencies" that I could point to. After reading about it, though, like you, I started discovering just how broadly and deeply autism has affected my life.
BUT, at the same time, there was already an understanding that I was different, not quite right. My family always made that plain, and I have asked my husband, multiple times over the years when various things have gone weirdly for me, "What is wrong with me?"
It just seems that we hear so much more about the troubles autistic people face and the deficits that we have that "I think I'm autistic" and "I've never had any problems from it" don't really go together in my head.
It seems like recognizing the autism is first and foremost a matter of recognizing the deficits and problems that we've had. So I'm curious about it happening a different way for others.
