I feel like what helped me most was not caring about how I looked and ignoring this need I had within telling me that I had to always speak well. Also speaking in front of a mirror daily helped a lot with removing a lot of the underlying uncomfortableness I had when I would stutter. It helped me embrace myself by just looking at myself speak even though it was gruesomely uncomfortable lol. Not sure if this would work for everyone but these are what helped me the most. You’re not alone there’s millions of people like you going through the same thing and I’m confident you’ll figure out a way to take back the power you’ve given your stutter over your life.
