I'm sorry you had a poor experience. It sounds like your therapist was inadequate for your needs. Not all speech therapy is the same. Think about all of the teachers you've encountered in your life. You had a slew of them. There were good ones and bad ones. Some terrible. I would hope at least a couple of great ones. You need to find a great SLP who specializes in stuttering. And this isn't easy. IDK how you've gone about researching speech therapy in your region. I think most of us generally google, use our medical insurance catalog, and generally struggle to find any good leads. I often suggest getting in touch with Speech Pathology programs at universities. Start with your local universities. See if they have programs or where the programs are at. Reach out to the academics in field. Search for leads that way. Academic networks are underutilized resources when you're seeking a specialist. It's going to take some legwork on your part to find the right person. Be critical in your discussions with them. At the same time, be open minded. Figure out what your goals are. Make sure that the people you consider are aware of your goals and are up to the task. I had a severe stutter from early childhood into my mid 20s. (never a fluent sentence. blocks that would outlast my lung capacity.) I did speech therapy in public schools (not effective.) I saw an SLP in my teens. I made little progress. I returned to that same SLP in my mid 20s and achieved fluency. The only difference in that 10 years was my attitude. Going from not believing that I could get fluent and not doing the work to actively seeking fluency and doing the work. I hope you can find effective speech therapy that meets your needs and helps you achieve fluency.
