My sis is sick

Heheh..I like Italic... Anyways, I am now feeling weird that my 3rd sister is crying in front of me, because she vomitted, had diarrhoea and is totally tired. I'm worried. at the same time freaked out. Now I'm searching on the internet for remedies or information about this sickness. Gastric, Gastroenteritis(Stomach Flu) and food poisoning are main suspects.Gastric seems to be the most likely one, because she did not eat lunch this afternoon. Whatever she eats, she vomits it out, sad, isn't it? Well, got to go, see ya.
