Don't mistake my professional demeanor as me not being the shy, socially anxious wreck that I am

While I'm at work, I can easily present myself as a well-spoken individual who's confident around others. Under the surface, however, I am anxious as hell! When interacting with people, I'm usually physically sweating because of it. No joke! Once it's finally over, I usually let out a big sigh of relief and maybe cringe at myself if I think that could have gone better. But see, no one ever guesses this because I'm good at masking it. I may still stutter and fumble around my words because I get so nervous around people, but that's about the only indication of it. That and the sweating, if anyone ever notices it, lol.
