This may sound strange, but I LOVE the fact that I have given my self a diagnosis... It's such a relief to know that I'm an alcoholic, now I know what I need to do. Not drink.
Many years ago my son was diagnosed with severe ADD, and I had the same feeling. After years of wondering what was wrong I finally had a label, I could educate myself (and him) and spend my energy dealing with it correctly instead of the continuous trial/error of the previous years.
