Actually I suspect that I might have Asperger's syndrome. I didn't interact with people for a long time, and thus forgot why I'm isolated. Recently I noticed that, even though I'm anxious to initiate a conversation, I hardly connect with people, even when I'm not anxious. It seems that I don't make eye contact the right way, if any, I say things I shouldn't say, and later I discover after some thought that what I said was inappropriate, I do't know how to stand and where to put my hands, .... etc. Things that I do that don't make others feel comfortable, and thus I feel uncomfortable even more than before.
