Murdering including killing your self is a sin. Murderers are not forgiven, from what I know. Self Delete is often a selfish act. I seriously suggest you get help. There are plenty of warm people in this world that would jump at the oppurtunity to help you through your problems. Don't give up hope! Your life might seem hard now, but I promise you there is a way to get through any issues you may have. If you need some want to talk to, I would be more then happy to talk to you via skype or something. You might not be the relegious type, but I suggest you say a prayer asking for help. You have at least one person right now worrying and caring for you, I'll keep you in my prayers. I don't know your situation with your parents, but I also suggest you talk to them.
