Feeling stuck

cemetaryraven11

I feel like my dr has given me an impossible thing to do, and that's to eat five times a day. The very thought of it scares me. I don't know if I can do this, I've always eaten a lot less than that to the point where what I do consume doesn't really amount to anything.
And I admit that sometimes even the smell of food makes me feel sick. I don't know how to even begin to try this.
