You might feel like you want to, but deep down you don't want to. The scars aren't worth it. The guilt that comes after isn't worth it either. When you feel the urge to do something like this, take a minute to think about what 'your about to do'. You don't need to hurt yourself because in the end, it isn't going to make you feel any better. Have you talked to a counselor about any problems you are having? It will help if you have someone to talk to. Any close friends that you trust enough to explain the problems you are having?
