You got diagnosed a month ago, you didn't get bipolar then. Whatever symptoms you had a month ago, when he broke up, you'd had--what?--all or most of the time you've been together?

I don't think the break-up had anything to do with your diagnosis or your being bipolar. Or even, as a mater of fact, with you. i suspect it's all your partner and you, your diagnosis, and your illness are just the excuse.

Just MHO. It still hurts, no matter what, but I think your partner was just generally not worthy of anyone with honest feelings & the ability to care about someone else.

Take care of you. Focus on your dis-ease. Learn to become as well as possible. Get strong enough to risk another relationship. Learn from this heartless jerk & move on.
