What annoys me is when I have a bad day and I don't know why. It seems mysterious things are going on inside my body to make me have a bad day and I can't see anything outside myself to make it bad. e.g. sensory things, people things, timetable things

At least I don't have periods anymore when I got one good week out of every month! That was hellish.
Too many to track.
Current situations (if that factors to processing space in background, if that contributes to internal stress), past situations (that IS stored somewhere with unprocessed emotions, trauma and whatnot), overall physical, mental and emotional health, stress levels (whether internal or external) and states related to it, mood levels, energy levels, hormonal fluctuations, external factors and consumables of varying sensitivity/insensitivities/effects from hunger and hydration to varying effects of sleep which may or may not be related to habits like screen time and diet.
And that's just the simplest as I can get for now.
Maybe I should quit tracking myself for a while and come what may...
Do something more immediate than the tangled mess that is myself.
