Why do I get dizzy feel odd and slightly anxious in certain social situations?

Just the other night a few of my friends and I had a nice drinking social. Everyone seemed to be having fun. Having a bit to drink I started acting a little crazy and erratic when a friend said to me "your such a weird kid" and "just act normal for once" it sounded as if they were just trying to antagonize me. This made me very self conscious a feel extremely uncomfortable because who wants to be perceived a crazy, weird, abnormal person. The next day I remembered it happening and told a friend about it all. He said not to worry about it everyone thought you were funny. But Im still sensitive to the whole thing and ever since then Ive just been uncomfortable with myself and felt nervous and weird in social situations. Yesterday I went on this rant about how I hate the media and reality tv I never really ever go on rants and after the rant i just felt real uncomfortable and a little loopy. I just felt as though people could sense it an were judging me. I just want to feel normal again.
