Well, small world...
I hate it... I know exactly how you feel...helpless, no one cares if you are sad, the "not-cool", but "not-weird" people being the only ones nice to you, the "weird" ones saying they are always better than you...in a very dumb way... Yeah...
I really try as hard as I can to ignore it, but it doesn't work at all... What I do is get quiet, drift off, and if people say stuff, ignore it, don't reactt, and just think of something... Wear an emotionless expression on your face, and then people will notice that something is wrong and will actually care a bit... If you do happen to cry, don't do anything about it... If people try to get your attention, look at them, wait for them to talk, and nod or shake your head at their questions of comments (If it's a comment, nod as if you're telling them you understand...), but don't talk... If helps to feel some sympathy from people... PM me if you need extra help, because I know a ton of stuff on that subject...
