Do I have Asperger's or am I just awkward?

It just sounds like you're a teenager who feels socially awkward. Its okay, I was like that too at times during my teen years. I still don't like being touched by someone I'm not comfortable with and the eye contact thing . . . . well that's an cultural thing as well. Many Americans don't like making eye contact for too long, we (for the most part) find it uncomfortable and only really use it in important/appropriate situations. I am like you with interacting with people as well. I like to socialize, but I have a limit. I love spending time alone and as long as you are happy, I don't see why there should be a problem.
