You have to do what works for you and one day you’ll figure it out. But for now, your stuttering isn’t going away soon. It will one day with enough work, but now you’re stuck with it. Emailing your teacher will delay your progress. Anytime the brain avoids a situation that seems stressful it considers that a win, and increases fear in future speaking engagements. I’m not trying to tell you what’s best for you, but consider this. The only way to overcome a stutter is by exposure, and by avoiding exposure you delay fluency.
