Very very sick need help!?

I need some help. Recently my fiance came down with some nasty sickness. He was puking and pooping water. Now I have it. My tummy hurts unbelievably bad and I can hardly walk, talk, move ETC. even typing is killing me. But I need answers. stuffs coming out of both ends of my body. I don't know what this is called. I need my belly to stop hurting but i cant take pills cause ill puke them up. I only have lipton(or whatever) iced tea, I mixed it with warm water but i don't like it. I don't have any ginger ale or anything like that. I layed in the bath tube for 2 hours and it kinda helped but no more hot water. Help pleaseee!
