I can’t say I haven’t. Ever since a kid up until adulthood I’ve questioned why I talk like this while everybody else around me talks so clearly and freely. Literally yesterday I was questioning everything after I was struggling to get words out and stuttering while talking to my wife. I’ve missed so many opportunities in my life because of my speech. Up until this day it bothers me and I can’t overcome it. Good luck to you friend. Don’t give up.
