The word depression can be misleading. Everyone has felt depressed at times over such challenging situations as a setback in one’s career or the ending of an important relationship. For most people, the sadness is temporary. Clinical depression (major depressive disorder) is more than just a temporary feeling. It is relatively long-lasting, can get worse over time, and significantly interferes with a person’s daily activities.
Major depression is a mood disorder that affects the way you feel about life in general. Having a hopeless or helpless outlook on your life is the most common symptom of depression.
