I am also bipolar. It took a while, but the doctors finally found the proper medication to control my mood swings. I have to take prozac and lithium. Without the meds, my family was not sure how I would react from one moment to the next. It is not okay to abuse your family even if an illness is to blame. Therapy also helped - for me and for my family. Also support groups may be available in your area for you for support and for him. Good luck and God Bless.
