Resteraunt tantrum

Last night we were out to eat with my inlaws. I'm a ftm and my son is 18 months. I have so much anxiety that people are judging me in public so when he started to scream I really overreacted and made a big deal about taking him to the bathroom. It took me three tries to pull him out of his high chair because I was rushing. I cried at dinner and haven't been able to even look at my inlaws since. Does anyone else have social anxiety? I'm so embarrassed. :(
