I'm an ultradian cycler. I think that's the same?

"Rapid" just means 4 cycles in a year (depressed/manic)

Ultradian cyclers like me can have multiple cycles in a day! But, I do that not very often, only once I hit a trigger. My cycles are actually kind of on a pattern. I go about 3-5 days of more depressive, then 3-5 days of more manic, then I have my episodes which happen a couple of times a month, depending on my triggers. I need to get back to tracking it, because it's kind of interesting to watch the graph.

Remember that song by 3 Doors Down "If I go crazy, then will you still call me Superman?" That's what your post reminded me of.
