In school it was tough but as I've got older I don't personally care about it anymore- people know what a stutter is and if I can't say something I just quickly say "I can't say that word" You'll forget about you incident in class with time, and it'll just become another time you stuttered, you might not even remember it. I know I stuttered loads between 9 and 14 years old but I can't remember a single time
