I'm 17 I'm in the same position as you that's why i don't have any friends and i already lose my confidence. because of stutter my life is hard i can't express my feelings or just talk like a normal person. It sucks when someone laugh i had a group presentation and it's my turn to talk but i just kept stuttering and whole class just laugh at me I was really embarrassed/hate about myself. And today i'm not talking a single word at school only when it's important i do talk to people. I hope there's a cure for stutter :(
