How to get over that gut/anxiety feeling you have when you are about to speak, but know you’ll likely to stutter? (Read description) So I don’t mean how do you get over that feeling while it happens, I mean how do you get over that feeling even after that situation has passed? I’ve had a job interview and while I waited in the lobby to get called into the interview, I had that horrible feeling. The interview went somewhat fine, but I’m back home and even after a few hours has passed, I’m still traumatized by that feeling I had prior to the job interview. Anyone know what I’m even talking about?
