I moved upstairs into the study to stay because of my self harm. Dad uses the study. No moving back downstairs because I will cut and my sister gets mad at me for being depressed. I need to move out of the study - what do I do?

The solution is simple; stop self harming. But, as you probably know, that is not as easy as it sounds. It becomes a way to express your pain, a way to relieve yourself, it becomes an addiction. Self harming is a destructive behavior, not only to yourself but to the people you love and the people that love you. My only advice is seek support for your depression and to seek help for the destructive behavior. Your family will help you, it sounds like they're trying already. Your friends will help you, unless your friends are encouraging this behavior, then find new positive friends that'll stand by your side. There are people out there that love you and want to see this behavior stop. Reach out to friends. They're out there. And know that you are loved.
