Thanks everyone for their support. It's been a shitty week.
I've been eating small doses of the most caloric dense foods I can find (mostly nuts, cheese, etc). I figure a week is long enough as I'm 5'6 and 120 lbs (F) and can't really afford to lose much more. The problem is, after a week, nothing sits well. If I take some digestive enzymes, it seems to help. I'll get there.
