Vomiting & diarrhea for 5 days straight can't keep anything down?

Vomiting and diarrhea for 5 days is a lot. Blood in your vomit is certainly a cause for possible concern. You may have had food poisoning, but even that by now should be getting better. If it's a virus, there's not a lot you can do, unfortunately. Old standards are ginger ale (the kind with real ginger, not artificially flavored, not diet), or real ginger tea; or 7-up (not diet); and regular, plain saltines. It is important that you keep sipping liquids (clear soda pop is very good for this). If the blood in your vomit continues, or gets worse, you need a doctor. If yours continues to be unresponsive, I would consider finding a new one. Also, you didn't mention a fever. If you have no fever, this is not a virus so you need to be checked for other causes. Good luck.
