100% it’s an anxiety loop. One time in my teen years I went to introduce myself and I got completely stuck on my name in front of a huge crowd. “Hi I’m Eeeeeeeeeee-van” “Evan, sorry” Now 16 years later I hyperventilate, hands shake, and will go out of my way to get out a situation and avoid introducing myself. Like I literally want to puke anytime I’m in a situation where someone doesn’t know my name. Anytime before that, I didn’t hardly ever stutter on my name. That tiny experience has completely changed my life and taken a word I might stumble on 1-2 times out of 10, to this life changing hell
