Any time my mood is off, my appetite decreases. I've been pacing most of the morning thinking all these terrific and horrific thoughts of heaven and hell, and just now at 2PMish I managed to take a break and eat a small sweet pepper.

My therapist told me to set alarms to remind myself to at least have a quick snack throughout the day. Hasn't worked for me as I turn off the alarm and go back to pacing, but maybe it's something to try?
