Instead of stopping after a few minutes, Depressed weeping continues for half an hour or more and seems to have a life of its own. Depressed MSers sometimes weep when they are not sad, and weeping continues long after they are ready to stop. Depressed people fall asleep when they retire, but they wake in the night to spend many hours tossing and turning. They feel alone and uncared for. They rehash unhappy events from the recent and distant past that are relevant only to the depression.
Sleepless nights increase fatigue.
Dishes pile up in the sink. The house is cluttered. Office work remains unfinished. Extra activities are abandoned for lack of energy. Body posture changes.
