Completely lost appetite

Seriously. I'm struggling to eat. I don't want to eat anything, it's probably lasted the past 4 days. Not even the bad stuff I shouldn't have. My stomach has been kinda upset for most of today, crampy, gurgley, frequent poops. 
I'm currently sitting with a legume mix protein bowl on my knee and my husband coaxing me to eat. Wtf. It's like I'm 2 and on a hunger strike. I know I HAVE to eat, I just can't.
