That isn't precisely what I'm saying. I don't know who put in those votes and thus I have ZERO idea what they're dealing with! They could very well ONLY be diagnosed with bipolar - it can in fact be the case but it is a lot more rare.

All I am saying is that non-rapid-cycling bipolar has fewer than 4 episodes per year. Rapid cycling has 4 or more.

When you add in BPD, I think you're more likely to be dealing with triggers that could ultimately result in an actual depression or hypomanic state. (I certainly find myself in episodes if I've been getting triggered enough). Those episodes may last a shorter time due to a consistent exposure to various triggers, but they would still be a bipolar episode if it persists. BPD episodes tend to last less than a day, so annnnny cycling that takes more than a day truly would not be BPD.
