Every one of us relates to your post. I began stuttering at age 4-5 and became fluent at age 70! My stuttering was caused by my anger and resentment from an abusive childhood. It was emotionally caused. Stuttering has both physiological as well as emotional causes and I was fortunate to have found my relief. Don’t give up hope, even at your age. Fluency is possible. There are even current phase 3 medication trials of a drug that treats stuttering. The next few years will be the most extensive in the treatment of stuttering.
