Sorry to hear this. I will attest that people diagnosed with bipolar tendencies can overcome them. But it is they, not anyone else, that must do it. Often, people with this condition make the decission to get themselves better when they are faced with a life changing loss; for example losing a job, losing their freedom (jail time), or losing someone they love. These are the types of things that often make people contemplate what they want to do with the rest of their life. Often, as long as they are not forced to make a decission, they won't.
One book suggestion I have for you is "Codependent No More".
