Hey :) unless your school is full of taunting demons, it’s nothing to worry about. I finished high school and on my way on finishing college with severe stuttering. Look at stuttering as a filter that helps you figure out who your real friends are. Real friends will be patient with you, and understand that it’s not your fault. Next time you present I highly recommend breathing and slowing down, even if you feel shy or awkward but give it chance ! Often times people stutter when they’re in a intense mood, so again slow down and mentally prepare yourself for what you’re about to say. Hope that helps !
