I’m 24. I always say, “sorry. I have a stutter” in a lighthearted manner. It works because them knowing that you think lightly of it breaks any future tension. Also, much of a stutterer’s anxiety comes from perception thats already primed with negativity. I remember telling my boss about how I always felt anxiety about my stutter. Now, he’s a fighter. Like he can actually fight in MMA. But he told me something that changed my perspective of my impediment: “if I had a stutterer, and someone made fun of me for it, I’d beat them up”. That utterance alone transformed my perception from a place of shame to a place of human decency. In other words, the expectation is that people should be polite. If they come off an ass, they can go <insert expletive>. Besides working on my perception of my speech impediment, I willingly made efforts to get acquire speech skills by joining speech team and theatre. It really helped out a lot. I still stutter today, but when I do speak fluently, I can execute my speech well. That’s just my experience. I wish you the best. Besides stuttering, when you turn 24, it’ll both feel like yesterday as well as a lifetime ago.
