Well about three weeks ago I had the stomach flu and lost around 10-12 pounds, but I recovered relatively quick. Then right after some personal issues come up and I've been depressed and haven't been able to eat. I've lost 21 pounds as of today and my stomach has shrunken. I try to eat even a slice of pizza and I can't finish the whole thing. I'm never hungry and whenever I try to force feed I just feel like I'm choking. I feel the weight just falling off of me and I feel weaker every day. Are there any methods that people use to kick start their appetite again? I really need help.
