I give up!

I hate my life, I get sick to my stomach thinking about having to spend the rest of my life feeling this way. Everybody I ever loved doesn't want to be around me anymore and I can't take feeling alone and hated all the time. Nobody cares about anybody else. Today in class my teacher told me to my face I was wasting her time so I cried all the way home on the train and now I can't breath.  I feel discouraged to ever go back... I hate my life.... I just want to dissapear.
