DEFINITION:
- depression
-
1. A hollow or depressed area; downward or inward displacement.
2. A lowering or decrease of functional activity.
3. A mental state of depressed mood characterized by feelings of sadness, despair, and discouragement. Depression ranges from normal feelings of "the blues" through dysthymia to major depression. It in many ways resembles the grief and mourning that follow bereavement; there are often feelings of low self-esteem, guilt, and self-reproach, withdrawal from interpersonal contact, and somatic symptoms such as eating and sleep disturbances.
