I've been trying to actually thoroughly track my moods for over a month now, and a pretty distinct cycle has popped up: 2-4 days up (and/or mixed), 2-4 down, and 2-4 days at baseline. Repeat.
It. Never. Stops.
I guess my question is, basically, wtf? This is exhausting...

Sometimes I can be basically normal for a couple of months straight, and then BOOM. Back to cycling. I also think they lasted longer, like months longer, when I was younger (especially the depressions, since the more manic-y stuff didn't start until mid/late teens for me), but lately it's like these 2-4 day swings, like clockwork (not without exceptions, sometimes they run longer, but still).
How do your cycles work?
