Thanks SmilePretty!
I figured out what's wrong is that I can go to eat something (even something familiar) and my first thought is "something [fill in the blank] is going to happen to me if I eat this" (generally, "I'll have a panic attack" or something along the lines of "it'll poison me" somehow). Even stuff I'm familiar with. I got myself a good old phobia going on. Right now I'm looking at my Ensure (which I drink to get the vitamins I need because I'm not eating healthy at all, in any fashion) and I can't drink it because I had three today, and I'm afraid of the fourth.
So stupid.
