I’ve coped my entire life. I still stutter in front of groups and every new person I meet. The way I’ve coped has evolved. I’m surprised you described this event like it was the only stuttering event in your life so far. I once spent 5 minutes just saying my name at a new job in high school. No one laughed but I wish the manager would have just stopped me after a minute and move on. I once recorded a 20 minute presentation shown to a crowd at an end of summer internship. Looking back it was super cringe. Now, I stutter with colleagues on international group calls. I’m not trying to one-up your story, just showing there are so many moments I wish were different, but none that keep me up at night. I move on and try my best the next time. Now I stutter mostly mildly with moderate to severe moments, it rarely alters my behavior. Like another commenter said, others rarely care. Why should I beat myself up over their thoughts?
