You are still so young. Have you tried looking in the one place you may have never looked before? That's what I did and I found the answer. Depression has a way of making us do things like that and feeling our worst. Christ is the only one that can give us a rebirth. I know when I have suffered depression, he was always there to talk to and bring me comfort. We don't have to go it alone, when we turn to Christ. He helps us fight our spiritual battles. Satan would drag us down, but God is so much stronger than he. When we turn to Jesus he can give us a brand new life, a brand new beginning and help us fight our battles. We can do all things through Christ who strengthens us. Those are just not words, but the truth, as I have witnessed it many times, even in myself.
