My Cousin is Very Sick.?

Today my cousin came over for dinner. When she got to my house she told me that she had not been feeling well the past day or so. While we were eating, I heard her stomach growling like nothing else, it was also larger than usual. Once, it growled big and loud and she got up and ran into my bathroom and projectile vomited for about 10 minutes. I went in after two minutes or so to hold her hair for her. After her vomiting spell was over she attempted to eat again when it growled again and she ran in there again an projectile vomited for another 5 minutes. After that was done she tried drinking water and again it growled and she projectiled again for about 10 minutes. After her last vomiting rage she lied on the couch with her head in my lap and i rubbed her stomach...something she did to me when I was little. I felt it when it growled this time but she didin't have to vomit. Then the gorlws got louder and louder until she ran in to my bathroom again and projectiled for about 8 minutes and then proceeded to have explosive diarrhea for about 6 minutes. When this was over, we went back to the couch and I noticed that her stomach had grown again. Felt it growl and she projectiled for about 15 minutes. Her shirt had vomit all over it so she took it off and her pants had diarrhea on them so she took them off...she doesn't wear underwear or a bra by the way. We walked back into the bathroom where for the next hour or so we switched from projectile vomiting to explosive diarrhea and back again...PLEASE HELP ME HELP MY COUSIN!!!
