I really suggest reading around on this sub, because you'll find many people discuss the tolls it takes in their daily lives. Those of us that struggle with mental health issues find that that it may hinge on or be exacerbated by our stuttering. Certainly anyone with a speech impediment know the anxiety that comes with speaking in a group. Think public speaking fear xMORE. All that pressure can break a person, make them shut down, or make them withdraw. Personally, I never let it stop me. But had my stutter been more severe, who knows? But one this is certain, there almost daily posts on here about coping with stuttering.
