are people who do not have insulation on their nerves,emotions and feeling. It's like a plugged in electric cord with the insulation stripped away leaving jagged nerves, emotions and feelings subject to highs and lows,ups and downs, manias and depressions. Unfortunately, there are treatments(dont work well) but no cures. Too,too many end up treating themselves with alcohol,pills,illegal drugs in a desperate attempt to deal with their daily hell. RIP Ghost.
