Depression
Depression: Introduction
Depression, also known as clinical depression, is a serious medical and mental health diagnosis that is associated with many factors, including the balance of chemicals in the brain. Depression can manifest as a large variety of symptoms. It is most often associated with feelings of sadness or despair that do not go away. Depression can negatively affect a person's ability to function effectively in the activities of daily living, such as going to work and school, caring for family, and taking care of basic needs. More than 20 million people in the United States have depression, according to the National Institutes of Health.
Depression is often thought of as experiencing feelings of sadness, "having the blues", or being disheartened. However, there is a major difference between having normal feelings of sadness in reaction to a situation, such as a death in the family, and having depression. Normal feelings of sadness, although painful, generally resolve after a short time. For example, feeling blue after losing a job is normal, and normally the feelings improve or resolve as the situation is addressed, by looking for a new job, going to interviews, and landing the new job. For people with depression, the experience of losing a job is very different. The feelings of sadness linger beyond a short time and intensify to the point that they begin to interfere with the ability to cope with the situation and look for a new job. This in turn can intensify the depression.
Feelings of sadness are also a normal part of the grieving process experienced when a person losses something or someone very important to him or her. For example, nearly everyone will normally experience some level of sadness after losing a loved one. Even very intense feelings of despair can be considered normal if they do not linger past a few days. Although there may always be a residual sadness when thinking of the deceased person, feelings normally diminish to a point that the bereaved person is able to continue on and function effectively in their lives. For other people, the death of a loved may be one precipitating factor in the development of depression or in exacerbation (worsening) of the condition, in which the feelings of despair and sadness do not go away.

Article Excerpts about Depression
Everyone gets the blues now and then. It’s part of life. But when there
is little joy or pleasure after visiting with friends or after seeing a
good movie, there may be a more serious problem. A depressed mood that
stays around for a while, without let-up, can change the way a person
thinks or feels. Doctors call this "clinical depression." (Source: excerpt from Depression: NWHIC)
