PDD, also known as dysthymia, is a prolonged and less intense form of depression that can last for years or even one's entire life.

Unlike MDD, or Major Depressive Disorder, which is characterized by extreme manic depressive episodes that last for short periods of time, Persistent Depressive Disorder is characterized by long-term and generally milder depressive symptoms that persist for at least two years.

People suffering with this form of depression are less likely to seek help, as many believe their symptoms to be an inevitable result of their life experiences and who they are rather than something curable that they could possibly be rid of. For this reason, PDD is largely undiagnosed and many suffering this never receive help or the treatment they need.

A person suffering from Persistent Depressive Disorder will probably agree with the following statements:

"I can't remember the last time I was truly happy."

"I haven't had a 'good day' in a really long time."

"I find it difficult to think about things that make me happy because it just makes me remember that nothing is permanent and everything good in my life will eventually disappear."

It is important that people with Persistent Depressive Disorder receive a diagnosis and the treatment and support that they need because people suffering from this treatable disorder have a high suicide rate and need to know that they are loved and that they don't have to suffer forever.
