Hey dude -- I'm sorry, that sounds rough. I remember being in a similar situation when I was 18 (I'm 31 now). I guess what I would say is that the stutter is never as bad as you picture in your head -- in fact, some people in the class might have been pretty impressed that you put yourself out there and said what you wanted. Whenever I have a situation where I stutter badly, I try not to be too hard on myself, even though it can be difficult not to feel that way. PM me if you want to talk more about stuff, I'm happy to listen!
