ouch ....that sounds like a proper bout of flu mate .......i had it a few years ago and i though i was dying , i don't get sick often but that was horrendous , don't worry about the food just get plenty of water or lemonade into you ...get well soon mate .
chicken soup ...home made ....cut out sugar , peanuts , chocolate .....most viruses feed off glucose.....plenty of liquids , not alcohol , other than that it will have to take its course, all the best.
