My aunt used to make homemade food processor sorbet for me and my mom when she was going through chemo and I donated blood and bone marrow to her pretty often (go being two of like 100 people that are AB+) so every two weeks we would both be laying around feeling like crap together, albeit she had the infinitely worse draw. My aunt would take frozen fruit (usually fruit she had cut up herself and frozen because she bought everything in bulk) and orange juice and hit in it a food processer until it was blended and serve some to us in a bowl. The rest she would put away in the freezer to keep it firm until we wanted some more. It takes seriously 2 minutes to make if you buy a 1lb bag of frozen berries instead of cutting up your own.
It's actually really healthy and it tastes good, plus you can get your fruits in. Have someone get you some Ensure or the generic ones. They sell them in cases at Walmart. They're meal replacements -- crappy ones, but at least it's something.
My psycho witch doctor grandma (i'm serious, she's a voodoo priestess and an accomplished herbal alchemist) has a cure for severe colds and flu that requires drinking a shot of hot, DARK (as dark as you can find it. The stuff she distills/ages herself in the spare off limits bathroom looks like tar) 100 or higher proof bourbon with cayenne pepper. It is to be immediately followed by sucking on a lemon wedge, and exactly ten minutes later should be followed by a cup of hot mint tea, steeped from fresh mint only. The shot opens up the lungs, the cayenne kills bacteria in the throat, and the mint oil brought out by the hot tea cures nausea and will give you back your appetite.
Try it out. It's nasty, but it works like a charm.
I'm sorry you're sick and I hope you feel better!
P.S. -- Since the law about sending toxic substance through the mail will hinder your ability to get ahold of the medicinal whiskey my Maman makes, your best bet if you decide to try the remedy is Noah's Mill. That's what I use as a stand-in. It's 115 proof, it will knock you flat on your butt, and it's about $30 a bottle. Just think of it as an investment for sick days, mmkay?
