overwhelmed.

so last night, i got home from school and had a billion things going through my head that are still bugging me now. who better to talk to about this then you guys?!?
im taking a class this semester with about 10 people in it. we all take turns getting up and singing and the teacher coaches us while everyone watches. now, these are the kinds of classes i should be thrilled about, because all i have to do is sing! however, yesterday i was sitting there the whole time thinking "omg, im going to sing so badly. everyone else is 938023958 times better than me. im bad!" and alas, it was not so great when i finally sang. i was so nervous that i was shaking and i had tunnel vision and i couldnt breathe deeply. so i guess i have pretty severe performance anxiety. when things like this happen, it makes me feel like maybe im not doing the right thing with my life. i mean, in the long run, what does it matter if i can tell you the meaning of a poem or not? who will care if my breath support is consistent? its not like im saving people's lives. one of the things that scares me the most is that im so worried ill end up doing a mediocre "temp" job that i hate forever. but the worst part is, i know that im smart enough to have done something meaningful.. i just dont want to waste my life away. im terrified of going back to this class and i dont know what to do. im going to talk to my teacher about it. he always says to just compare myself to myself, but its so hard not to compare myself to other people. and when i do that, i feel like im the worst one there. :(
so i just wanted to get that off my chest. thanks for reading
