I am not officially diagnosed with an ASD, but something called Nonverbal Learning Disorder, a condition very similar to Asperger's (which I am considering undergoing testing for), and you sound similar to me. I was diagnosed with depression when I was younger. Then Borderline Personality Disorder. Then Bipolar. And now Schizoaffective. I have problems with social skills, talked early, was always very clumsy, etc. I had to be taught how to run properly in grade eight. My legs went everywhere. It was quite embarrassing, the teacher pointing it out and teaching me the correct way.

Anyway, if you think you may have an ASD, definitely talk to your psychiatrist about it. Sometimes they will refer you to a psychologist, or sometimes they can do the testing themselves. It's worth it. Good luck!
