ABSTRACT
Those who have experienced a marked depression describe first and foremost their lack of energy, or desire to be bothered to do anything. Even talking may seem to take effort. Instead there might be a desire to retreat to bed, to sleep and perhaps to cry. On the other hand, sleep may be difficult: the person may wake in the early mornings and lie for long hours unable to get back to sleep, feeling particularly low at this time. Appetite and enjoyment of food can also sometimes be affected.
