You need to tell yourself that stuttering is just what you do. It’s not bad, it’s not good, it’s a disability that you have. I’m 35, I just graduated law school, and I have a moderate to severe stutter. I’ve gotten an unbelievable amount of shit from people over the years. It used to weigh me down. I used to just take it. Not anymore. I’m valuable to my community, I’m loved by my friends and family, and when people start shit I simply say “I’m disabled and I don’t appreciate being mocked” and it is Amazing how people fall all over themselves
