Why do I still want to commit suicide?

I have been on medications for deppression, yet I keep trying to commit suicide. Do you go to hell for that? I keep over dosing on every pill, but it doesnt work. I tried strangling myself but it didnt work. Im 15 and cant learn to love myself as a person, I hate the way I look, I have no friends. My momis barely home to spend time with me, I have nothing to live for
