Glad to see you have found peace! I also achieved my own "worry-free" stutter, but much sooner & faster(It took me around 2 years, from 16 to 18). I made a YT channel explaining what worked for me & what didn't. For anyone interested in beating their stutter & also being in the best shape of their life ----> [https://youtu.be/\_Oz4uz8YOlA](https://youtu.be/_Oz4uz8YOlA)
