Hi Frank,
Sounds like you have an awful lot going on at once here. It must be frustrating at times trying to figure out your best course of action.
Therapy is a good place to start though. Are you on any meds for your bipolar and other mental disorders? I wonder too if your brain injuries are making it difficult for you to make healthy choices in your life. If your thinking is skewed by the surgery and injury, I think it's important for you to look into specific therapy for brain injured individuals. There are ways to retrain your brain and coping mechanisms that you can institute to help you in your day to day life as well as learning ways to make better, healthier decisions.
I wish you well Frank in your quest to better health.
