I'm sorry to hear that. Wow... that really sucks, I haven't broken up with someone yet (i haven't been in a relationship) so my practical knowlege is a bit thin, but theoretially, I say that you shoud go and talk to someone. Especially if had a pre-existing depression. Talk to someone you trust, teacher, parent, or maybe a therapist. I've found that it always helps to get your feelings out. If you can't talk to anyone, try to write your feelings down. Get them out as effectively as you can.
