That guy must be reported. Totally unacceptable. That said, life will get immeasurably better when you come to peace with being a person that stutters. My 16 year old son refused to accept it for years. Refused speech therapy because it never helped. Continues to hold out for a cure … psychedelics, whatever. We found a therapist (who stutters himself) and the first few sessions were ALL about changing his mindset. I thought it was impossible…:but it wasn’t. And it was a game changer. The more he learned, the more he wanted to learn. And the more at peace he became. There is a documentary called When I Stutter. You can rent it on Vimeo. It gave my son and me so much hope and encouragement. Please watch it. YOU are not defined by your stutter. You are so much more. You need to find the right therapist to help you see that. It will change your life. My advice is to find someone who stutters and is involved with the National Stuttering Association. Hang in there. You just haven’t found the right therapist yet.
