Are you acting out or is it just difficult for your family to deal with your depression, because going to a boarding school for troubled teens would probably be a really bad idea. If you want to get help away from home, you should try a partial hospitalization program instead, although it would be hard to do if you're not out of high school yet (if you are, take a semester off and try that).
