I’m a girl. Most of the bullying I experienced as a kid for my stutter came from other girls. I have no idea why. When it comes to trying to get rid of that fear of stuttering in front of girls or really anyone ig, honestly you just have to weed out which people are worth associating with. If you’re in like a work situation where you cannot choose to stop associating with a coworker that’s targeting you for your stutter there are steps you can take with HR to try to get things sorted. In any case, always stand your ground. Don’t stand for being made fun of. I never spoke up about any of the torment and mockery for years. Don’t be like me. Always correct people who think it’s okay to be shitty towards you for your stutter.
