The actual diagnosis may not be important, but there are psychiatric/emotional issues that get in the way of making good choices/building healthy relationships. When it comes to medication, each person responds individually, effects/response differ, and many of the medications used are used for multiple reasons, we often don't even know why something works, or does not. The field of matching medications to genetics is a new and interesting one. (eg: HepC: a genetic test can tell which, if any, medication you are likely to respond to----& each person is unique...)
