Im not gonna tell you to just relax or w/e. You will stutter from time to time its gonna happen. Accepting your stutter is really important in school. I used to let my stutter rule my life in my early high school years. But now I realise it was just a phase in life. Im way more happy and social since I stopped being afraid. If people dislike you or w/e cuz of your stutter theyre not worth your time.
