sugahorse, I think it's good that the T is looking at BPD. If you have been misdiagnosed and/or it's a dual diagnosis the correct diagnosis will help with the treatment process. BPD mood issues tend to be reactive, and a shorter duration. A person with BP can have a mood present for no reason and the episode tends to lasts longer. If you aren't already I would suggest tracking your mood. This mood tracker is excellent, and is password protected, but if you don't put your settings on private other people on the site can look at your mood tracker. I use the journal function, so I keep mine private.
