Been there brotha. Still have the issue where it’s hard to add my 2 cents in a group conversation, especially a fast paced one. Cuz people would talk over me when I stutter. I either say it louder, or I stay quiet until I have something really interesting to say. But tbh, no matter what you do, how embarrassing it might seem, it doesn’t matter in the long run. Keep going brah, make friends, get experience, because all this pain leads to useful growth and social skills after high school.
