I'm not convinced that there's any kind of therapy that can heal stuttering. Many of us, including myself have been to so many therapies but the results are the same, instead you're always blamed for not believing enough in your abilities which is bullocks. I think the next part should be exploring available medicines to rewire our brain power and neural pathways. I'm not sure if this is possible yet but I think that's what science should focus on more than anything else. But let us all pray about it and that God heals us from it. I'm getting so much better each day because of believing in him and asking him to heal me.
