Can anxiety make me feel like I'm going to throw up and give me an intolerance to basically.. all foods?

I feel sick all of the time. It has been gradually been getting worse as the anxiety gets worse.

My biggest fear is that there is something really wrong with me, and everyone is just calling it anxiety, when the anxiety is a side effect of whatever is wrong. I almost puke after every meal, I never feel healthy at all. I haven't felt hungry, fully, or normal in months. I don't feel nomral ever and I am at the very end of my rope.
