Hypoglycemia-End of my Rope

Hi, and thanks in advance for reading. I am actually up (from only 2 hours sleep) because I am kind of just at my wit's end. I have come to the realization in the past few days that I may have this condition, particularly after some very embarrassing panic episodes while shopping. The problem is, I have absolutely NO appetite. My body gets hungry, but the thought of eating food disgusts me....well, besides coffee. Has anyone else experienced this?

Also, what are some good high-protein snacks? Any tips that help you handle this condition more efficiently?
