I know this is no comparison to what you've had to deal with but I was first diagnosed with Major Depression and Obsessive Compulsive Disorder. It was very soon after that that the OCD dropped off because it was ludicrous. Soon after that, I became Major Depression, Recurrent. This stuck for 17 years. It was wrong. Finally, it was Bipolar II. Then I had a psychiatrist tell me that he thought I was actually Bipolar I. Frankly, I don't care what they call me as long as the medications they give me take care of the symptoms and I can function normally.
