Nothing about your stutter is your fault so please listen to the others and take your time, and speak in whichever way is best for you. I’m starting to realize with my own stutter that when I’m stressed, I focus too much on how others are perceiving me, often in a super negative way, and then I start to almost reject myself. You DON’T need anyone’s approval, and you HAVE to try to appreciate yourself and the courage you have for going into that interview, discussion, or stressful situation generally. Be as proud of yourself as we are of you
