The point about manic depression or bipolar disorder, as it's now more commonly called, is that it's about mood swings. So, you have an elevated mood. When people think of manic depression, they only hear the word depression. They think one's a depressive. The point is, one's a manic-depressive.
I have a type of bipolar that swings up and down all day long. There are significant mood swings within a day, within a week, within a month. I go through at least four major episodes a year. That's really the definition of bipolar rapid cycle. But I have ultra-rapid, so I have tiny little episodes all day long.
