I was answering a thread this afternoon about cycling. It occured to me that I seem to have both slow cycling and rapid cycling, if that is possible

The rapid cycling happens on a weekly or biweekly basis, but is usually either from depressed to more depressed or depressed to normal (as normal as I will ever be anyways), or normal to high.

But then looking at my life overall, there are the slow cycles which happen over a year or even longer. For instance, in the last 10 years there has been three distinct times where I crashed and burned, mentally then physically, and could not work - leading to the logical complications. In between those lows has been the high points, where I was a super achiever, could take on anything and coped with everything life threw at me.

Has anyone else noticed this or am I just slow to notice in myself what others already know?
