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.
