I’m not trying to troll you or anything by saying this. But why so many speech therapists? A good one that you stick with should be able to provide you with strategies to manage stuttering. Look to see if there is a speech therapist in your area that specializes in fluency. Unfortunately, there isn’t another field of practice that is trained to handle stuttering, so unless you go that route you’re limited to online research and support groups. Check to see if the NSA has a local chapter in your area if you’re in the U.S. https://westutter.org/chapters/locator/ Stuttering is incredibly frustrating and misunderstood, not to mention isolating. I get it. Please don’t give up on therapy and try to keep an open mind to having your goal be stuttering management instead of a cure for it.
