Not sure if you're referring to high school or college, but just enjoy your time in school. Most people don't give a fuck that you stutter. Yeah some kids are assholes, but there's nothing you can do to change that. Everyone is preoccupied with their own life. Everyone is different and some people might even have it worse than you. Once you realize we're living on a spec of dust floating in a vast universe and nothing really matters it makes life somewhat easier.
