I am so sorry you're having a terrible time of it lately. Sometimes all the bad stuff happens all at once and doesn't seem to give us a chance to get our legs back under us.

It sounds like your ex and your friends are not able to cope or help support you with what you've been going through. It could be because they are scared of what you've been going through and a lack of understanding, but whatever the reason is, they have behaved badly towards you as a result and that's a bummer.

In a way, it seems like you're grieving. Not only are you trying to cope with the other traumatic events in your life, but all this got added to the heap. It sounds like this guy isn't mature enough to handle a real relationship. Relationships are all fine and dandy when everyone is happy and doing well, but if he can't hack it when the going gets tough then he wasn't ready for a mature relationship.

It's going to take time to get over him and move on and that's okay. Chalk it up as a learning experience and hopefully in a few years the only thing you'll say when you're reminded of him is, "What was I thinking?" I hope everything improves for you soon.
