Keep going. I know it sucks. You are going to have an interviewer that gets it one of these days. Either they stutter or knows and loves someone who does. Focus on communication and always remember to breathe. Take a long pause, breathe in. Practice the strategic pause. I stuttered my whole life. Ended up a professional speaker. I give speeches to hundreds of people. Have presented to CEOs of major corporations. Congress. I still have blocks but I give myself grace and have the confidence in knowing a pause and a breathe and a mental reset will let me ease into the word. I don't care if that looks awkward. They can wait
