The best thing you can do is get over it. It’s not going to change. The only thing you can do to change it is the way you react to it. Sounds like your reacting with in a negative manner like these people are purposely trying to make you feel uncomfortable. The truth is, we make people uncomfortable. They don’t know how to act around us, and justifiably so, they don’t interact with stutters very often. We get a spectrum of reactions from pity to just ridicule. The only thing you can change is how YOU react to it. Also, dont let these reactions change the way you go through your day. Continually seek these speaking situations and they get easier.
