Annie, I can see my moods in my handwriting too! When I get really depressed, I use less pressure and my writing is even sloppier than it normally is.

Mountains, it's ok to journal about stupid things. Everyone who keeps a journal does it from time to time. That's what the journal is there for-it's your safe space to write about anything and everything with whatever style fits your mood. Does your t have to read your journal? I used to share entries with my ex-therapist, but I was very selective in what I shared.
