I think it’s because addicts choose to take that first step. You did not choose to be bipolar but the heroin addict chose to put the needle in his/her arm the first time. They may not have chosen to be addicted but they willingly set themselves on that path. I also think it’s a political correctness thing. Let’s face it, some people are their diseases but no one’s going to say that. If your bipolar disorder consumes your life and ruins your relationships and environment, then, yes, I think you are your disease. However, if you keep it in check by whatever means, then, no, I don’t think you are your disease.
