Welcome! I was diagnosed as bipolar many years ago. The doctors were not too much help to me, but I went to AA and they eventually fixed all of my problems. Your currect feelings sound just like someone who has been sober for less than a couple of years. It often takes many months for our nervous system to get back to normal. You are doing well with the meetings and the exercise. Don't quit before your life is transformed to something beyond your wildest dreams.
Good Luck,
Jim S
