I'm not a psychiatrist but it almost seems like there a bits of bipolar as well as maybe Borderline Personality Disorder, only because you bring up relationships being affect and how you become clingy.

However, my bipolar definitely disrupts my relationships with friends and stuff. I might have a commitment and whilst going manic may go out partying and sleeping around only to have to explain where I was to my friends and why I didn't show up.

The long term parts as well as the depression seem accurate to bipolar including the distance from others.

Definitely bring it up to your treatment specialist.
