I was diagnosed with autism spectrum disorder about 1 year ago. I wasn't surprised but I really expecting such a diagnosis either. About 6 years ago I had a consular say I was extremely introvert. That was the first I ever heard of such a thing. That got me doing some research. During that I read that ASD has similarities to introvertism. With the others problems I have, I kind of wondered if that's what it was. I isn't really interested in talking to a mental health pro about it though. Over the past few years, I've tried taking some college classes. I noticed I had extreme difficulty with assignments involving writing such as essays. That problem was nothing new since I've had difficulty with a lot of things involving writing for numerous years. I finally decided to talk to someone about it last year. They did all kinds of tests and asks all kinds of questions. The diagnosis does answer a lot of questions about past events in my life and why I do some things or feel the way I do.
Going into little mode helps me a lot. I kind of wonder if this part of me has something to do with having ASD. I've always wanted to have stuffies, wear diapers, and do other little type stuff even when I was a kid. I deal with it the best I can. There are what I would call "tantrums" on a rare occasion. I can kind of tell when they are coming and do what I can to prevent them.
I voted other since I believe autism and aspergers are grouped under ASD now.
