Im 14 and i want to commit suicide?? PLEASE HELP ME :(( ?

I read the whole thing, and it sounds like you have way too many problems to be fixed over the internet. If you have a school counselor, go talk to him/her about your situation. And you're not ugly, or fat. Underweight to be specific. Also, you are not going to be a failure unless you let yourself be. You're not worthless and right now you really, really, need to go talk to someone about how you're feeling.
