If I make changes in my environment could that cure my bipolar or at least help me cope?

Absolutely can be. Helpful, yes - cure - no. Most professionals agree that bipolar disorder is a life long issue much like heart trouble, hypertension or diabetes. Environment and life style have a great deal to do with bolstering treatment and certainly helping one cope better, with physical and mental disorders. Don't put excessive weight on an environmental change though, it's only a help not a cure.
