That right there is your hope. It's your anxiety of knowing you might stutter and someone is listening, not that you do stutter. I used to stutter so bad in school if someone asked me my name I couldn't even say it. Now at my work no one even knows i stutter and just finished up inspections with fire Marshall's. Just practice being calm that's what worked for me. Stay. Calm. Control breathing calmness like you're almost sleepy. You'll be fine and you won't stutter anymore takes some practice
