I'm sorry that you are having such a bad time. However, please consider that the way you reacted was probably a result of your depression. I understand your ex's feelings about it being "over". If he hasn't experienced depression personally, then he has no way of knowing how the things he says or does might affect you. I truly believe, though, that if he doesn't want to try to help you, then he wasn't right for you. Are you receiving any kind of therapy?
