I totally agree. Look up "del ferro method" I went to del ferro once because they claimed they could cure stuttering by using their method. They use a speaking method with costal breathing because it has to do with your diaphragm your diaphragm stutters when you also stutter And i expierence it myself as a severe stutterer, if you us ethe method you don't stutter And after a week of using the method 24/7 with every single word you utter it really improved my stutter i stuttered way less then before. So i believe if you do that long enough (like maybe a year or so) you can complete get rid of the stutter. The teacher there that taught me once was a stutterer himself. He is completely fluent now because of that method and now teaches other people the method to cure their stutter. But unfortunately because i went there when i was still way to young to understand the consequences of stuttering i gave up the method too early because it felt shamefull to talk that way in front of my friends at the time. It did improve my stutter so its not that severe anymore. But still my biggest regret ever.
