a state of depression, lack of energy, bad mood and unwillingness to do anything, strongly connected with
autumn/fall, raining and cold,
windy weather; a kind of
seasonal apathy that sometimes also covers winter (when winter looks more like autumn, without snow etc.)
Mark is a cheerful person, great to hang out with, but somehow his mood
depends on the weather. When
autumn starts, he is in a fall-falling state: does not want to go anywhere, walks
around the house without any purpose etc.
