Yes, I realized the same some time ago. However, I believe the trauma is not in the stuttering itself, but in the experience of others’ reactions and the shame associated with it. It’s a form of CPTSD for me. I think I large part of trying to heal is dealing with embedded feelings of shame and deeper fear of abandonment and overwhelm. Then we can challenge ourselves to meet experiences of stuttering in safe situations, so we break the association of stuttering = bad and turn it into a neutral. EMDR is helping me, I have to say.
