Are you unintentionally making stuttering worse?

Are you unintentionally making stuttering worse? Hello, I just got done with my speech session today and my therapist made a comment that made me think. How many of you, when you think about stuttering or get anxious about stuttering….results in a worse stutter? I was conflicted on this because there was been plenty of times where I wouldn’t even think about stuttering yet I still would have a bad stuttering moment. Thoughts?
