Stuttering is a joke compared to the rest of the issues people can have(trust me). Id recommend you therapy and meditation. I had neither, so I relied on substances, and they helped bring me into the social world, which healed a lot of my problems and put me on a path to fluency. Now looking at things "maturely" I shouldve just stopped whining and meditated when I was younger. Self control brings immense power, I think people who stutter are just more "evolved", so its alright to take some alone time to make love with thyself and come out indestructible. I wish you the best, there are always solutions to problems; go deep asf.
