There is nothing called "decline" in a psychiatric patients life, its either full on happiness or nothing...
The word "decline" has been changed out for the word " nothing", if a fellow patient has it then for some that is a clear signal to stay as far away as possible, as if you were fighting against the plague..
The "nothingness" much like the endless destruction you would see in the film "Never ending story".
Its like standing on a cliff where you look down on a big fall that you know is too high and dangerous for you to control, so you will end up at the bottom in pieces.
