This isn't an advertisement. But I'm based in the UK I'm 19 had a stammer since I was 3. I joined the mcguire programme at 15. The same one garreth gates did. The best thing I every did. They are world wide. I'm now a coach on the programme and help new students and struggling grads. Maybe it's worth reaching out to your regional director for the programme and joining. We will always be stammers/stutters but stammering in control is better than stammering out of control. But if you have any questions feel free to get in contact with me
