I found out I had this very recently, back in November.
I was talking to my mother, just venting really, and getting worked up about life and other things such as that, and she told me that I was displaying a lot of traits of Asperger's syndrome. I was really confused about it as I said, because I never saw any of those aspects in me.
She discussed it with other members of my family (my uncle has it) and some other people. We didn't want to get a test done or anything like that, because all that costs money. My mother is a teacher in special education who teaches socially impaired people, including a lot of people with AS. She was pretty clear when she said I had it.
We have since gone along to this club for people with Autistic spectrum disorders and it's pretty clear to me now that I DO display an awful lot of the AS traits. I am pretty held back in school which I hate, and I'm unfortunately as quirky as anything.... I never got any special ed myself because we found out so recently, but I'm glad at least now that I have some label to put on why I behave the way I do.
I wouldn't call myself self diagnosed because I DIDN'T diagnose myself and my mother who works with children with AS diagnosed me, and after going along to the club, all the instructors and other members know, and can tell I've got AS. We don't have much money to pay for a diagnosis anyway....
Nice story everyone?
