Please go talk to the school counselor or the speech therapist in your school. A really good speech therapist could talk you through how to deal with situations like you explained. There’s a great organization called FRIENDS Who Stutter that has support groups specifically for teens. Might be worth checking out. Their virtual meetings are online on Wednesdays at 7:30 PM once a month. Actually, the next one is this week. https://www.friendswhostutter.org/virtual-teen-groups/ This Reddit thread is a great way to find supportive people. Keep coming back. We’re here for you.
