Yup, it gets really hard to eat. Especially hard to even shop for yourself. I remember, once, taking all day to get dressed and looking presentable only to drive to the store, walk around in a haze because I couldn't even relate my need for sustenance to the items all around me, and went home to bare cupboards empty handed. Cans of garbanzo beans and frozen vegetables have gotten me through a lot of hard times. My family got me a small deep freeze and have filled it with fish etc so that I have something when the agoraphobic or dissociative feelings surface. Also now have meds that work. Exercise is so so so fucking important too. Internet hugs, if you want them. Your last sentence is 100% correct.
