Thing is I sleep at any time; for an hour or 2, and wake up with a little more stamina to face my problems; or at least a calmer approach to them. The question was how to cope with an extremely bad mood.

Wouldn't this same theory apply to the myriad of people who say they have seen ghosts? Either every tale of a ghost is wrong or they exist. Same as ETs. Maybe ghosts are otherworldly creatures.
