I can't say that I have any advice since I've never managed to make a relationship work (more due to PTSD than bipolar) but I did want to say that I hope you feel you can hang on here a little longer and see if you get more help than hurt. I hate to see people leaving like that and would like to think that someone might be able to provide some help that counters the bad.

I wish I could help more. I just wish you'd stay a while as it sounds like you need someone kind to listen. Do you have a therapist?
