Depression is a state of mind characterized by feelings of sadness, despair, emptiness, hopelessness, helplessness and worthlessness and loss of interest or pleasure in nearly all things. In some cases, the affected individual has a lack of energy and motivation.
Major depression is a serious medical illness affecting 9.9 million American adults, or approximately 5 percent of the adult population in a given year. Unlike normal emotional experiences of sadness, loss, or passing mood states, major depression is persistent and can significantly interfere with an individual’s thoughts, behavior, mood, activity, and physical health. Among all medical illnesses, major depression is the leading cause of disability in the U.S. and many other developed countries.
Depression is a psychological condition that changes how you think and feel, and also affects your social behavior and sense of physical well-being. We have all felt sad at one time or another, but that is not depression. Sometimes we feel tired from working hard, or discouraged when faced with serious problems. This too, is not depression. These feelings usually pass within a few days or weeks, once we adjust to the stress. But, if these feelings linger, intensify, and begin to interfere with work, school or family responsibilities, it may be depression.
