As stutterers, I feel like we can’t hide shit. No matter how good I can act, if I’m Insecure, or anxious, or really trying to make a good impression (ie, NOT stutter)? I wear it on my sleeve and am blocked from the get go, then get all bound up and have to force words out, which I feel makes me and others uncomfortable, which makes me self conscious, more uncomfortable, and I stutter worse. If I’m calm and cool? As in I don’t give a shit and generally not trying to make any kind of impression? Close enough to fluent for me. Figuring this out was a big deal for me. I basically just needed to get secure enough with myself to use my tools publicly, and it took away the power from my stutter, meaning I can work through it without the snowballing anxiety. So maybe that’s a place to start for you.
