Phobia of vomiting, could this be the flu?

my friend went out drinking the day before yesterday and she came home feeling nauseated but she thought it was just a hangover.. but then she was with her sister and her friend who were previously sick... her sister was only sick for a day and her other friend was sick for a couple.... today which is two days after she feels nauseated and made herself throw up but she never gets sick, she said she just has a headache and feels sick to her stomach could this be the flu and if it is home come she got it 2 days after? and what are the chances of my and my son getting it????

Hey! I understand COMPLETELY, the reason I found your question is cuz I'm looking for info myself because I was around some lady at work that said she had a stomach virus. Well, did you have any direct contact with the girl? did you drink out of her cup or eat off of her plate? Or were you anywhere close to her vomit? Or did you touch her hands and not wash your hands afterwards? Supposedly those are the only ways you can catch it, and supposedly it's not airborne (REALLY hope it isn't, haha).
I'm pretty sure you won't get it. Don't worry. And usually if you have a stomach virus you will throw up automatically, you don't have to make yourself throw up.. So maybe she was just stressed out and felt sick? Or maybe she was worrying herself sick? (happens to me, like right now). And if she did catch it, it takes a couple days to develop the different symptoms. Oh, also, did she have diarrhea? Usually people have that when they have a stomach virus.
I wouldn't worry if I were you. :) Just always wash your hands plenty of times each day, and you'll be pretty much protected. Oh, and if somebody vomits, RUN AWAY!!!
haha
Good luck :) Hope your friend feels better!
