Sounds to me like you may be a little bit manic. You said that you've been put on an anti-depressant for social anxiety disorder a month ago. Did you start feeling manic before or after you were put on medication? A lot of anti-depressants have side effects like what you are talking about. You should go and see your doctor (or any doctor) and talk to werf about your medication and behaviors/feelings. You could just need a change in medication to get rid of the side effects.
PS. Don't stress about being prescribed an anti-depressant for social-anxiety disorder-- Anti-depressants are prescribed for a variety of different problems, not just depression.
