Is bipolar your only diagnosis? I ask because sometimes these kinds of behavior can also fit with borderline personality disorder, and there is a specific treatment for that if you are diagnosed with it. If not, I would recommend finding a CBT counselor (cognitive behavioral therapy) or even looking for a book about it...I think you can get workbooks too. I've had some CBT counseling and it does help with how to learn new behaviors to replace inappropriate ones. Also, talk to your doc about it and see if your meds need to be adjusted...
Take care, and I hope you can get things sorted!
