Help me die less

I have been dying so much in League lately. I am at the point where I've tried punishing myself, punching myself didn't train me. So now I've tried cutting myself and I am running out of spaces to do that. I only have my wrist left. I've been getting told to kill myself every other game, and maybe they are right..maybe I am so fucking stupid I deserve to live..I just want a last shot at getting better before I do that so any advice is welcome.

Edit: This isn't my real account, I don't want people to see how much of a failure I really am
