100 percent at least to me i stutter more when i think about stuttering and worried about it. But something that I have been able to do is trick my mind, whenever im presenting and its a big moment where any person would be nervous, Id try to stay as calm as possible and even though I cant control my stutter, staying calm tricks me into thinking I could control my stutter. Therefore I stutter less in those anxious moments. At least thats my theory behind it lol I don’t quite understand it at all.
