Anxiety and Digestive Issues: Can Anyone Relate?

I feel as though my anxiety and digestive issues go hand in hand. When I am nervous my stomach gets very gassy and I feel the need to poop a lot. My stomach will make noises or air will become trapped from holding it in and will make a loud noise that sounds like a fart. This gives me the most anxiety to begin with, but nothing I do helps. The anxiety causes it, which then causes my anxiety to increase. This bothered me a lot in college to the point where I would try to sit in the back farthest away possible from people just in case my stomach would make a noise. I have even skipped class or tests on many occasions from being anxious and self conscious about my digestive issues. Can anyone else relate?
