Symptoms of frustration

 

Depression overview

While everyone feels sad from time to time, major depression is very different. Major depressive disorder or clinical depression causes you to experience feelings of sadness, loneliness, or a loss of interest in things you once enjoyed. When these feelings occur for more than two weeks, doctors may diagnose this as major depressive disorder. These symptoms are a sign that you need to seek professional help. Talk to your doctor if you have symptoms that may indicate depression.
