Read this: https://www.amazon.com/HOW-STOP-STUTTERING-LOVE-SPEAKING-ebook/dp/B09FM612RD I’m in my thirties and my stutter started getting much worse (all fear/anxiety in my head). Then I found this book and all the good reviews. It’s helped a lot. It’s nothing crazy, but he’s really passionate about fluency and betterment of your mental state.
