There is nothing I can say which will change the way you feel right now. I'm sorry for what happened to you; nobody deserves to be treated that way. And it is especially bad to have this happen on top of depression. And I don't think anyone could keep a person in your position from thinking about ending their pain, but I just ask that you not act on those thoughts. There was a time in your life when you didn't feel like this and there will be a time again when you don't feel like this; you have to wait it out. I know that's easy to say.
If you find yourself planning some action, would you please call a suicide hotline, 911 or a friend? And let us know how you're doing.
