If you have the money you can skip this process and book an online session with stuttering-specialist.com . His name is tim mackesey he was a stutterer himself and now he treats people who stutter . He charges like 190/ session . If you have the money , go for him directly and if your stutter doesnt improve i will personally pay you back the money. And if you dont want all of that , start by reading the book and practicing voluntary stuttering everyday to desensitize yourself to the fear of stuttering.
