Clinical Depression

Clinical depression, more commonly known as major depressive disorder, is my textbook diagnosis.  Wikipedia, the definer of all things when on the Internet, defines major depressive disorder as this:

Major depressive disorder is a mental disorder characterized by an all-encompassing low mood accompanied by low self-esteem, and by loss of interest or pleasure in normally enjoyable activities...

A person having a major depressive episode usually exhibits a very low mood, which pervades all aspects of life, and an inability to experience pleasure in activities that were formerly enjoyed. Depressed people may be preoccupied with, or ruminate over, thoughts and feelings of worthlessness, inappropriate guilt or regret, helplessness, hopelessness, and self-hatred. In severe cases, depressed people may have symptoms of psychosis. These symptoms include delusions or, less commonly, hallucinations, usually unpleasant. Other symptoms of depression include poor concentration and memory (especially in those with melancholic or psychotic features), withdrawal from social situations and activities, reduced sex drive, and thoughts of death or suicide.
I use the term "clinical depression", because that was the term first told to me.  Depression is everything those commercials with the sad music and greyscale imagery suggest it is.  It took me years and an eventual breakdown to get the strength to get help for it, but eventually I managed.  I encourage anyone who feels they may be depressed to seek help.
