I require help with depression?

Hey there. I think that explaining it to your parents would be a great start. You need the support of your family, I don't know your family. Have you had any counseling for the abuse? If your not keen to take medication then I think seeing a counselor would be really helpful to you. One that uses cognitive behavioral therapy. They can give you the tools to change your thinking to help you overcome your depression. I hope you find a way out, your young and have your whole life ahead of you, being 13 is a difficult time for most people, but things make more sense eventually.
