I'd agree with the other user -- my stutter sucks sure, but it's not comparable to the disease that severed my spinal cord. A disease is also generally from an organic cause, like there's something structurally wrong that can be evideced and most stutters do not present with an organic cause and if they do, then the cause is the disease, the stutter the symptom. Like, my spinal cord injury is not a disease -- but it is the symptom of a disease.
