If you think it's bad, you could see a doctor. Maybe a professional can help you relieve your social problem.
I'm like you, esther, only probably not as esther-ish. I'm not the spazzy jumpy hugging kind, I'm more of the kind of person that makes the jokes, laughs a lot, and gets themself into weird situations.
BUT..... I fail in one social area. I have such a hard time making eye contact. gah, I suck at it. I always try to look into peoples' eyes, but then I end up thinking to myself "... this is awkward, I think laser beams are gonna come shooting out at me any second.." it feels uncomfortable and weird...
for the eye contact thing, try to look into people's eyes, even if it seems weird to you, it won't to them. Just don't show that it feels weird to you.
one time my teacher was like "tess, why do you look so pained when you talk to me?" xD
