I'm glad you asked this because I am wondering same thing - I have a bipolar dx and have tried quite a few drugs.
the only ones I think even help me are like klonopin or valium for anxiety and rage probs, general just needing help calming down.
Although I get depressed too - "med resistant depression" they called it... so those meds didnt help me.
But I fet the bpd profile pretty well too -- so confused right now! Pdoc appt tomorrow, so freaking nervous and annoyed that I even have to go.
