It is quite normal for people to feel sad after confronting major life events such as losing a job, getting divorced, moving from home, or having a beloved friend or family member die. Most people begin to to bounce back from these stressful events within a few weeks' time. Some people, on the other hand, experience clinical depression that goes beyond merely feeling sad or grief-stricken. This may involve feeling empty or unloved, the inability to enjoy things, feelings of lethargy, the inability to concentrate, feeling irratable, eating less, crying more, and other symptoms. There is hope, however, in the fact that depression responds to treatment. Thus, it is important to recognize when something may be wrong.
