Negative Manipulation Through One’s Injury

By injury, please feel free to substitute the following: chinks in one’s armour, weaknesses, trauma – mental anguish, emotional disturbance. Then there comes the predictable debate about whether the injury is self-induced versus being externally derived, or the interplay of both, its age of onset, its severity and duration (acute or chronic). All the same, injury becomes an opening for a thing. It could be the light and a healing. Or it could be its antithesis. Are you able to tell when the former or the latter are in action, and if not, is it because of the severity of the injury?
