Depression

Depression is an illness that involves the body, mood, and thoughts.  In addition, depression affects how a person eats, how much he sleeps,  what he feels about himself, and how he thinks about things. Depression is not the same as a passing blue mood. It is not a sign of personal weakness, or a condition wished away. People with depression cannot merely “pull themselves together” and get better. Without treatment, symptoms can last for weeks, months, or years.

A mood disorder marked especially by sadness, inactivity, difficulty in thinking and concentration, a significant increase or decrease in appetite and time spent sleeping, feelings of worthlessness and hopelessness, and sometimes suicidal tendencies.
