My mouth physically twitches when I think and I bite my tongue or make a clicking sound with my tongue. I wouldn't mind so much if it didn't hurt. Kills my train of thought in its tracks. But maybe it is directly tied to stress/anxiety/depression. I'm so used to being depressed and anxious I hadn't even considered that being a factor in the severity of my stutter, thanks for the insight. I had noticed it being better after a workout, which would make sense. Hard to be anxious or depressed immediately after a workout.
