I think I have this disorder.  It's called Essential Tremor.

I really can't control certain situations... just two days ago, I was randomly chosen to read my thesis for a paper, and I couldn't speak at all, I felt I sounded retarded, or really wimpy and fobby, but I couldn't control it... thinking back, it happened to me serveral times.  In Microbiology, I failed pippeting into this tube because my hands wouldn't stop shaking.  I was teaching one time, and my hands started shaking, and my voice shakes... gahh this is so embarrassing.

I did a little research though, and it says what I already know: reducing sugar, getting more sleep, and excercising regularly. Also, I think I truly do need more exposure.  Exposure around people, and just talking more.  Having friends definitely helps, but it's overwhelming (I had TWO friends in ONE day yesterday).  It's all because I'm scared.  It's fear.  (Or did my anxiety come before fear?)  All I can do now is prepare... I just want to stop shaking and stuff and once I get past my fears I think I can be super cool.
