i’m 67 years old and have stuttered all my life and am a substitute teacher for 17 years. does your school have speech therapists? your pediatrician has to write a note to your school stating you’re a stutterer (Moses, President Biden, James Earl Jones, country singer Mel Tillis, the patron saint of stuttering Notker the Stammerer, google The Stuttering Foundation, a speech therapist will give you tools, techniques, & confidence teaching you how to breathe, sing and communicate. There’s tension in your neck, throat, larynx, tongue and singing helped me relax and control those muscle groups. Wear a tshirt that says “I stutter, what’s your superpower” or something clever and find people who love you anyway. Keep your physical hygiene, wardrobe, hair on point. God bless you!
