Strongly agree with this. I’ve been using Apple’s “mood” log for about two years now, and it is extremely helpful for me to have a concrete view of the history of my general affect.

“This entire month I’ve been feeling good, I want to pinpoint why,” or “it’s clear since stressor X entered my life, my affect is lower; how can I resolve this?”

These long term trends are harder for me to track without data. It might be easy for others, but not me!

As someone with Schizoaffective Disorder Bipolar Type, if you are not diagnosed with a mood disorder, tracking "swings in you mood" when you have no clinical disorder seems like a disorder of its own.

I have had people tell me they were "manic". Then I showed them videos I took when I was manic and they see what I mean when I tell them they are not manic.

We have come to a place where we do not want even normal fluctuation in mood, and that is a illness of its own, but it is a cultural illness.
