I'm new to this site, and I don't know if this has already been a topic of conversation....

I've been stuggling with maintaining relationships for several years. And I don't mean boyfriend/girlfriend, just regular friendships. I get irritable and angry over something that shouldn't be an issue, and next thing I know I've ended a pretty good friendship. I've lost so many friends this way, and most of the time it is my fault because I couldn't control my emotions. I've been diagnosed as Bipolar II which I'm not sure how I feel about it. There is an obvious mood disorder and my mood stabilizers help when they're at the right dosage.
At any rate, I'm curious if anybody else struggles with this because I feel like there is something wrong me that I can't keep friends around. In my 29 years on this earth, I can honestly say I don't have many friends.
