They do. I'm in the UK and got one with the NHS but didn't find it helpful. They want you to "accept the glitch and learn to live with it", which I don't really want to do. They taught me techniques I already knew and had used. I can't remember if I stopped going on my own or if the therapist thought it was enough but it didn't help me. Maybe another therapist would do good and actually help, maybe not. I've work in a call centre for over a year now and at the start, I was always thinking about stuttering and while I did, it wasn't too bad and I was happy with it. Now, I feel my stutter has become worse, especially in work while taking calls and I can't figure out why. My stutter has never been as bad as it is now, while in work, and it's affecting me mentally and also affecting my job. I don't fear taking calls and I don't become afraid or anxious until I've had a bad stutter and then I start to have some fear for the rest of the day, or until my next break but the cycle repeats. You'd think after being so comfortable for the first year of my job, my stutter would improve. It hasn't. It sucks we all have different triggers and different fixes but I'm glad some people are able to improve their stutter and even become fluent again. Hopefully you can find something that works for you and it sounds like you may be improving too ! Best of luck to you
