Trust me, it the depression will stop at some point. I used to feel the same way, and even put a pair of scissors to my throat, but i stopped myself and realized that Hell is going to be unimaginably more painful than any kind of pain any human being could ever experience on earth. So i did not kill myself but still kept hurting myself, slamming my head on the wall, scratching at my skin, biting myself, etc. But at some point it just started to go away, and i even forgot about all of that, and i am doing pretty fine right now, and have been doing fine for a few months now.
So please, if you are being serious, do not do it, it's the pussy way out, and be strong, and don't let your emotions control you.
