Dysthymia, also known as persistent depressive disorder (PPD), is a chronic form of depression. It has many of the same symptoms as major depressive disorder, but they are often experienced with less intensity for two years or longer.
People who suffer from dysthymia often lose all interest in their usual activities, impacting their job, social life, their family life, and essentially every aspect of their life. They may have a persistent feeling of hopelessness, have poor self-esteem, feel unproductive, and are usually very unhappy with themselves in general.
