I have a lifelong stutter. They ‘fixed it’ when I was in the 3rd grade with strawberry paste in the back of my throat and lots of practice _not_ saying “um” and “uh” but just staying quiet.
But even though it doesn’t com out, it’s still there. The gap. The pause. The place-where-the-stutter-is. I’ve shrunk it enough to where it’s imperceptible _outside_ of me, but internally, I always know it’s there.
That’s why I took to writing my thoughts far more than speaking. I’ll speak when I have to and I can do it, but it’s always ‘extra effort’ to keep the stammer from coming out.
Lots of deep breathing and putting on a pleasant smile.
Same. Brain moves faster than mouth mechanism. Gets jumbled up. Sometimes there’s no proper words either, which makes it harder still.
