Trying to figure out my cyclothymic bipolar patterns

I’m trying to figure out my cyclothymic bipolar patterns, but the shifts are subtle enough that I second-guess myself. I’ll have stretches where I sleep less, talk more, start too many plans, and feel unusually confident. Then I’ll slide into low motivation and irritability without a clear reason.

What makes it confusing is that I can still function during both phases, so I’m never sure whether it’s actually a mood change or just stress and a bad week. I’ve started tracking sleep, energy, spending, and how social I feel. Hopefully seeing it written down will make the pattern easier to recognize.
