Over the years, I've seen my diagnosis go back and forth. Some pdocs have said they strongly felt I might be bipolar. Some said they didn't think that. Now, I kind of believe that many doctors sort of want you to pick the diagnosis and then tell them symptoms that support whatever you pick. I know that sounds odd, but I really believe it's true for those whose symptoms are not real clear cut.

Regarding the meds, I think it's entirely possible to be helped by SSRI's and still have any one of a number of other diagnoses, including bipolar disorder. My experience has led me to believe that there is no predicting what med will, or will not, help anyone. It's basically all trial-and-error.
