Yes, there are things we CAN do to try to make this illness called bipolar disorder as manageable as possible. Diet is a factor, and exercise, and seeing a pdoc, and getting a good night's sleep, and seeing a therapist. I work hard to distract myself from worrying about it. If I have to go to the hospital, then I will. It is a pain to go through all that, but most hospitals I have been in haven't required the notorious trip through the ER. My docs call ahead.
I am sad that you are hurting so much right now. Please talk to your doctor(s) and follow the instructions.
