Ive been in this position before. please dont do it. its not worth it, why do you feel you need to commit suicide?
I know when i was in this situation there wasn't alot that anyone could tell me that made me feel better. and i hated when people told me "you can feel better" uhh i hated that. but please i would feel bad if you did it.
Go to a counselor, trusted adult, you can call 1-800-SUICIDE its a hotline to talk about this. but i ancourage you to talk to someone in real life like a counselor.
you can pm me anytime if you wanna talk, ive been there and it sucked.
