Maranara,
I know exactly where you are coming from. I suffer from Bipolar as well as several different personality disorders. It is possible that both co-exist. And yes, I believe that one can feed off the other. I live it, and have many different pdoc's and T's tell me the same thing.

I can tell you from experience that when I'm suffering from a mixed episode or a manic episode (I rarely get hypo manic.) My personality disorders are much more prevalent. They really are out of control as well.

My Pdoc and I have a idea about that. When I'm not struggling w/ an episode, I have the ability to control the impulses and what not that follow along w/ the personality disorders. Therefore, I'm less likely to act out on them. But when I'm struggling with a bipolar episode, I can become violent at something that I normally would be able to brush off. I can give you many different examples of that happening.

So, Maranara, please stick around. Both can be managed, and managed well. They do coexist. However, I do recommend that you speak w/ a counselor.
