Unfortunately bipolar follows no rule book, and seems it can do whatever it wants and when ever it wants. It's difficult to tell the difference between mixed episodes, ultra rapid cycling or manic!

To further complicate things I get 2 different manic phases. Hypermanic, and manic. But it isn't always being full of joy! I can be extremely irritable, bursts of rage, then be ok, racing thoughts. I feel cheated out of the "high" one expects when hypomanic or manic. Lately it seems I get the bad manic episodes, which is often confused with borderline personality disorder. Indeed I might have both or there may not really be that much of a difference to matter. Again there are really no rules, and much of it is guess work. Definitely in the bipolar spectrum, possible borderline. Best wishes to you!
