Youv'e got to learn to control your though process. And it can be done. Try to occupy your mind. Find things to do to take your mind off of your situation. Seeing a counselor would help. They are professionals and they can teach you how to do this. Or find a good book on depression and read it. We can get caught up in thinking about
the same thing over and over. It is no fun I know. But there is help. Writing here helps too.
Best wishes to you.
