It gets easier. At some point your desire to express yourself and get shit done exceeds the desire to reach some arbitrary value of social normality. You'll stop caring so much about what others think of your stutter. You'll lose a lot of that dread that feeds your anxiety. You'll begin seeing interactions as a team sport instead of a competition or something performative. You'll gain better faith in strangers. As all of this happens, you will gain some fluency, too. I was also diagnosed with (and even hospitalized for) social and general anxiety in my late teens. I spent all of my 20's unable to use a phone or order my own food. But now, I do it like it's nothing. It takes a lot of time, but the more you step out of your comfort zone and confront your fears, the more you will see them as the fake neuroses they are, and the less power they will hold over you. Always remember that, most often, it is not our stutter holding us back. It's our fear of or embarrassment of it. And though we can't control our stutter, we can control how we choose to live with it. Taking accountability for my own choices was a huge step for me.
