Why do people get depressed?
Almost everybody gets depressed in relationship to some kind of disappointment or loss. Psychiatrists put the label "major depression" on episodes that are persistent, lasting weeks or months rather than hours or days, and involve not just unhappiness but also a loss of interest or motivation.
Sometimes people even become suicidal. Like less severe depressions, they are usually the result of loss or disappointment or some similar stressful event.
Some individuals are probably more vulnerable to experience more severe depressions, and depressions do have some propensity to run in families.
