I disclosed my stuttering to my therapist in our first session. She believes that my anxiety and task avoidance are due to me always avoiding any stressful social or speaking situation during my formative years. So now any semi-stressful situation causes me to avoid it at all costs. I also went to a three week intensive speech therapy program about 15 years ago. That program reduced the severity of my stuttering, but more importantly it made me become more accepting of it. Good luck in therapy, I wish you all the best!
