I think it's all the same and we can choose to do either or. The problem stems from not being able to get past a certain part, always falling into the pitfall right then and there. So say we first stutter on the beginning part...then we can stop and just go silent but really we know we're trying to push our way out when what we're really likely doing is locking it in tighter like a chinese finger trap. I think when we stutter the first sound or repeat a word and hit that part we're stuck on, we're just hitting the block over and over. We can choose to stutter, then what they call block, then try again and stutter (so we're always falling into the block at that point). I'm not sure why speech therapists even differentiate it as something entirely different. Even though it may look different on the outside, we know that we are going through the same issue hitting the block that we can't get past. To stutter is to hit the block. To block is to not be able to get past it either way. It's good to be aware of this rather than confuse ourselves thinking one is any different from another or that we can't choose to do either or. We might just fall into it and lean into it but even in the moment we can so called stutter, start repeating again, or try it all again at any time. ​ So instead of leaning into it, something that might help is to breath out and say it out the breath out, letting go of the block and pitfall we keep falling into. Trying again basically but with awareness and purpose not to set it up the same way again.
