7 Signs of Seasonal Affective Disorder
SAD is a form of depression, and it shares most of the same symptoms. The two most common symptoms of depression are feelings of sadness and hopelessness, and losing interest in activities—such as socializing—that you normally find pleasurable.
If you experience these symptoms every day for at least two weeks, it’s a sign of depression. If you feel this way only during the fall and winter, and if these symptoms disappear during the rest of the year, it may be a sign of SAD.
