Sadness and Depression
Everyone feels sad sometimes. You may feel sad for different reasons. You may have experienced major life changes or disappointing events.
Sadness may cause you to react in different ways. You might cry, listen to sad music, or spend more time alone.
Being sad is a normal reaction in difficult times. But usually, the sadness goes away. When a sad mood lasts for 2 weeks or more and interferes with normal, everyday functioning, you may be depressed.
