Hey man, sorry to hear you're having a rough time right now. Being a person who stutters in high school is rough. It sounds like you are trying hard to put yourself out there, that's a good thing. I'm 34 and can tell you things get better, people grow up after high school and you will too. My advice for the moment is to talk to people about your stuttering. I know that's tough but it really disarms people and can give them a better understanding. Please, please, try not to get into fights - I know that can be tough too but in the end it will be much better for you. Try to find and meet up with others who stutter. It can feel really lonely sometimes, you are not alone.
