I can totally relate to this… tbh I’ve shaped my personality around it. I’m someone who actually loves to talk (half the time I be talking with myself in my head), because of the way I stutter, I slowly turned myself into a quiet, shy guy just to avoid drawing attention to it. issa curse, for real. To answer ur ques, something that’s helped a bit for me is practicing breathing exercises, especially before speaking. Also, making a list of alternate words for the ones I usually get stuck on helps smooth things out a little.
