I had a severe blocking turn red in the face stutter when I was young. Slowly got better as I slowly cared less and less about what others thought of me. By the age of 40 it was 90% gone. Now at 50 95%. I think the more you focus on it and try to fix it, the more attention you bring to it the worse it gets. So working on yourself not the stutter. So try a spiritual journey instead. A guided mushroom trip may be helpful. Go J. With the intention of analyzing you and your stutter. The answers may surprise you.
