Evening.
I do not have bi polar however a few of my friends do have this condition. The only advice that I can give, as a bystander, is to eventually find the right meds so that you can keep on an even keel as possible.
And when you do find the right meds don't stop taking them, even when you feel that you are coping well and can do without them.
As I say, I'm only a bystander to friends who are riding that particular rollercoaster of life.
