Doctor can’t give me anything?

I was throwing up 12 times yesterday from everything If I drank sprite, threw it up, water, etc. Didn’t even eat. So went to the hospital and and they ran blood work and said all is good probably just a stomach flu and said they can’t give antibiotics bc a virus has to run its course. I thought it was such a waste of time for one. And money. Two, i have extremely bad pains as if someone is squeezing my stomach and punching it and keep vomiting. What do y’all think? Again, can’t even eat or drink anything and they seemed to not give two craps. This is a emergency room that just opened and isn’t rated the best so I would like y’alls opinion, thank you.
