I went to many therapists and nothing really worked. the only thing I learned is that if you don't stutter when you are alone, that's mean your stutter comes from anxiety. I noticed people are taking two ways after that: 1: Anti-depression and anti-anxiety drugs which will make you not give a fuck about anything so you don't stutter 2: people went into Anxiety therapy and supports group, or hypnosis. For me I am trying hypnosis nowadays, and if it did not work I will go to drugs, but I am sure it will work. many people were better after it.
