I think you need to be 100% vulnerable with others. Begin telling other people you stutter and tell them about your other emotions too, such as pressure to be a good father. Because if you don’t you will continue to suppress emotions. You need to have an outlet for your emotions. You need to create trust with your wife that she will love you even though you stutter. I think this will help your speech, because all the fear you’ve built up trying to hide your stuttering is causing tension and making your stuttering worse. So I would really recommend the Dave McGuire course. They have an inexpensive self help book on Amazon called “Beyond Stammering: The Mcguire Program for getting good at the Sport of Speaking.” You can have the book downloaded onto your phone in minutes if you get the Amazon Kindle app. The book will go through psychological reasons for stuttering, give you a breathing technique, and inspire you to get out and practice speaking. The program will be fear inducing but use the people closest to you for support. Keep practicing the techniques and follow what the book says. Then I recommend reading “Redefining Stuttering” by John Harrison, someone who stuttered for many years and was part of the National Stuttering Association for many years. You can find a free link to the book if you google the title. If you can’t find it I will help send you a link. I was surprised to find the book for free after seeing it was sold out on Amazon. It’s time to start living free man! The first few months of vulnerability will be tough, but take it one step at a time. You’re already doing great, you’ve accomplished so much externally, but you must now focus on the work that needs to be done for you to feel better internally
