I agree. I never stutter when I talk when I'm alone. When I talk alone, I don't think about my speaking in terms of fluency. Because it makes sense to speak fluently. But when I add a person, then I feel pressure (perceived stresses) which causes stuttering, for example I get the negative (pressure) thoughts: "I don't have time to remove my doubts of fluency" so I don't even try to say "you CAN speak fluently", I completely disregard confidence in fluency and accept the fact that I will stutter (after all, I believe that I can't do anything about it). What is your opinion? How should I remove the doubt of fluency (so that I believe that I CAN speak fluently)? (I mean, in my experience, when I remove the fluency doubt, then I experience fluency so how can I deal with the doubt so it doesn't return?)
