PTSD is a terrifying thing to live with. A kind heart tainted with fear, that slowly evolves into insanity. Pain, drained out by "thrill". Distraction, always running away. Tic, after Tic. How could one deal with it? You're right, no one could. Instead you drown all of it out with a "simple" hobby. All of that devastation, fear, sorrow. It is forgotten with countless skewers to the skin.
