You just learn to accept that it’s just part of what makes you, “you.” I don’t get anxiety from knowing I’m about to stutter (or that I will eventually stutter) anymore. The feeling that never really went away is the embarrassment after I stuttered, however, it’s now a very mild feeling of embarrassment. It took about 9 years (I’m 34 now) but I would say I’m content with how I speak. It took all that time of seriously just accepting that I will probably stutter forever. I stopped apologizing for stuttering and I also stopped breaking eye contact when I speak. Now I would say that I’m a pretty effective public speaker (my job demands this skill) and I always tackle the daily speech I need to give with the following mindset: “I need to say this, or find a way to say this.” I hope you accept it. What you have to say is just as important as what anyone else has to say, you just have to believe it and project it with your attitude.
