Emil Kraepelin quotes:

The patients often try to starve themselves, to hang themselves, to cut their arteries; they beg that they may be burned, buried alive, driven out into the woods and there allowed to die. One of my patients struck his neck so often on the edge of a chisel fixed on the ground that all the soft parts were cut through to the vertebrae.
