Maybe ask your Pdoc if the prozac could be part of the problem. Lots of people with BP I have problems taking an AD. I have Bp I and any AD slings me into a hellish Mixed with in 2 days. So I will never ever take another one.
Just a thought.
Until then fling every coping skill you have until something hopefully sticks. I really feel for you , mixed is pure hell on earth !
Stay safe
