I have a stomach virus; why do I throw up everything I eat?

I'm 14 and havent thrown up for about 7 or 8 years now, so of course I was afraid of throwing up in the first place. I threw up late last night and at first it was a lot but then it was very little and I gagged so much and could barely breathe. It was so horrible! And then, I tried to drink some lemony water and after about 15 minutes I threw up. So every 15 or 20 minutes I'd puke. Pretty much, I know that anything I eat or drink will cause me to throw up, why does this happen? It's really annoying and I want to get better by Monday but I highly doubt it because I have a really upset stomach and it got really bloated and won't go away. My mom says drinking lemony stuff or Ginger Ale will help, but won't that make you throw up even more? I need help, thank you to all answerers!
