Hi "MP"

It takes a while to get on the right med combinations and amounts. Are you talking to a psychiatrist about your state of mind? You also might want to look into CBT; see if there is a psychiatrist/ Therapist who does group Cognitive Behavior Therapy for people diagnosed as Bipolar. This can teach skill sets for the type of thinking that exacerbates depression.

I responded so late, who knows what your current state is, hopefully you are feeling better. Don't feel hopeless, these states of mind are never permanent.
