It’s not a matter of ‘way of thinking’.. it’s an actual speech disorder that recent studies found that stuttering is linked to reduced blood flow in the area of the brain that produces speech! Not to invalidate your experience. If it worked and that’s what you were hoping for, I’m happy for you, but it’s also a bit weird, are you certain you had a speech disorder or was it social anxiety or fear of public speaking (not saying that’s easily solved with changing one’s way of thinking either) but I was wondering.. are you implying that other disorders/disabilities/illnesses are curable by changing one’s way of thinking or is just stuttering and what makes stuttering any less real than other disorders and do we really want to add to the stigma that stuttering isn’t actually a thing because “so what everyone stutters -when they’re nervous-“ so it’s curable with self-discipline? Yeah idk :/ I’m very skeptical about all this but hey, good for you.
