Idk why but this text is hard for me to understand. I feel like I have dyslexia now haha. But basically what you're saying is "is the main therapy acceptance rather than overcoming stuttering?"? If so.. not much has changed with that approach. Learning to not resist your stutter and allow it to be a part of interactions without pushing it away is key to "overcome it". And that also means acceptance. To act as if you've chosen to have it. Once you are no longer in opposition to your stutter and you're cool with it, and you're cool with yourself.. stuttering no longer is something to resist or push away. It's what resists persists. Once you're in that state of being cool no matter if you stutter or not, stuttering no longer is a problem. Acceptance in my terms isn't "giving up" but it's learning to maximize your happiness with who you are, and learning to navigate your existence in a way that is most fulfilling to you.
