I've never been evaluated, so I don't have a dx. I learned about AS about six years ago when trying to find answers about my son's odd behavior.
The more I learned about it, the more I began to realize that it explains so many things about me, like why I've always had such a hard time in job situations, and never understood what I was meant to be doing or how to do it. Why I have always felt like everyone around me has been told some great secret that I have not been told. Why popular TV shows about people in social situations make so little sense to me (who the heck has a life like THAT?) Why I feel so incredibly drained after a party. Why I've only had a couple of friends in my life, and they have always been people who protect me in social situations, and who say things like "you're so cute and funny" when I do something that doesn't match what all the nts are doing, and when I didn't intend to be cute and/or funny. Why I get so caught up in my knitting or Lego movie making that I don't realize it's gone dark and I haven't made dinner yet. Why I have so much trouble making a meal. Why I can't stand inane small talk. Why I sometimes accidentally will go from saying nothing to suddenly spewing out my entire life story to someone I hardly know, and scaring them away. Why it takes me so long to do any task, because I get stuck or I'm daydreaming. Why I used to get so nervous around people that I would shake, and sometimes still do. Why I despise the telephone. Why I can feel really strongly about something, or enthusiastic about something, but not be able to explain it to another person. Why I'm totally invisible to strangers, except for on the occasions when they come up to me and say, "smile, it's not so bad" when I was just daydreaming. Why I am so uncomfortable in shopping malls. Why I'm susceptible to depression. Why I nearly flunked out of high school despite the fact that, at some point, I was told I had a genius IQ. (Not sure when or how that was determined, or if that's true. If it is, fat lot of good it's done me).
So, there's nothing really major, or that would be super obvious to people, but I can't think of any better explanation for all that stuff.
