A couple years ago I just decided that I didn't need to let it bother me. At some point I realized that my biggest internalized issue was stuttering around other people (ie. ordering food, making appointments, etc.) and that led me to realize that I personally was not bothered by the fact that I stutter. Other people's reactions were what bothered me, and ultimately it's my concern and my concern alone. If other people have a problem with the way I talk, then fuck 'em.
