Food is not digesting! Help!

Okay I need some food ideas. For a week now I have been sickish to my stomach. The flu hit hard on Monday and I havent recovered. Everything I eat now gives me indigestion or worse. My stomach aches continually and when I eat it all sours during the digestive process. Okay now that may be too much info but what in thunder do I do? Are there certain foods that will settle the stomach? Since Wednesdays weigh in (recall I weighed in a day early) I have gained 2 pounds while not eating more than usual. Nothing though seems to be digesting. I obviously still have a virus. So help me people. What foods should I eat? I even considered fasting to give the entire digestive system a rest. Im desperate here!
