Atypical depression is characterized by symptoms that are almost the antithesis of many of the symptoms of major depression. While depressed people typically sleep less and eat less than normal, people with atypical depression tend to sleep more and overeat, gaining weight rapidly. Atypical depression is more chronic rather than episodic and usually begins in adolescence. People who suffer from this condition especially sensitive to rejection. For unknown reasons, atypical depression is often harder to treat with antidepressant medications or psychotherapy than other types of depression.
