As part of the journey to good mental health, I started journaling a couple months ago. I started with my own version of bullet journaling. It helped me personally take notes on why I might feel some way. It was a good way to hold myself accountable for behavior that can affect my feelings. I’ve also decided that recording feelings of everything from tiredness to boredom is probably something good to track.
I’m still figuring out what works for me as far as mood and mental health tracking. I think it’s important to know what might trigger certain feelings, as well as what some feelings are caused by. So maybe, in the future, I think it would be good to try to associate certain feelings to my mental state, instead of saying they came out of nowhere.
