Is it normal nervous tummy

Everytime I am around someone else besides family ESPECIALLY if they make me nervous I always get the worst stomach pains and fart a lot, it happens everytime I'm a little bit uncomfortable which just makes me more uncomfortable because I'm scared they'll notice which makes if worse and causes me so much anxiety.Some days I'll forget about this problem and it won't happen because the problem is the only thing that makes me nervous around people, but then once I remember I get nervous and the viscious cycle starts again. It's actually pretty funny because I will say I'm not unnatractive or overly antisocial I model and am pretty outgoing but can be a bit shy sometimes and no one ever knows the true reason. People don't seem to even notice a smell or anything, so I think it might all be psychological like a phobia of farting in public? haha sounds weird but is this IBS or IIN?
