I was recently diagnosed with bipolar II by my pdoc. However, I am not sure whether I really believe in the diagnosis. I do have spurts of high energy and I have a history of having depressive episodes that last for days a time for no apparent reason. But I don't think the high energy really is enough to impair functioning. I have an ADHD diagnosis and always attributed my hyperness to that diagnosis. I feel like it's sort of a matter of opinion what "impairment in social, occupational, or other important areas of functioning" means. Because I've also read that with bipolar II, the highs can actually lead to productivity and the person might actually enjoy the feeling.
