I agree. I was SO GLAD when I finally knew what was wrong with me. Until then (I figured it out myself and then after my pdoc at the time was clueless I got in to see a world-renowed specialist in bipolar who confirmed things and gave me a clear picture: severe variety, rapid cycling, mixed episodes, would be hard to treat (he had no idea how hard), could be helped with meds available then but not really stabilized easily although perhaps new meds would come out that would do that. He was right on almost every front. The 6 months I went to that clinic for a clinical trial they taught me so much and I just felt more and more "this is ME!" and was glad to finally understand.
