Exactly, a self defeating, self fulfilling prophecy. Thinking about my stutter, I have to be 100% mentally focused and talk with purpose which definitely comes off as a tryhard but that's how I can get my thoughts out clear. I can't be chill and just casually speak smooth and fast. The smoothness of my talking is kind of like Shaun from the Good Doctor. Sometimes I can speak casually without stuttering too much and sometimes I need to fully mentally think and talk a bit more slow.
