Symptoms

Persistent depressive disorder symptoms usually come and go over a period of years, and their intensity can change over time. But typically symptoms don't disappear for more than two months at a time. In addition, major depression episodes may occur before or during persistent depressive disorder — this is sometimes called double depression.

Symptoms of persistent depressive disorder can cause significant impairment and may include:

• Loss of interest in daily activities
• Sadness, emptiness or feeling down
• Hopelessness
• Tiredness and lack of energy
• Low self-esteem, self-criticism or feeling incapable
• Trouble concentrating and trouble making decisions
• Irritability or excessive anger
• Decreased activity, effectiveness and productivity
• Avoidance of social activities
• Feelings of guilt and worries over the past
• Poor appetite or overeating
• Sleep problems

In children, symptoms of persistent depressive disorder may include depressed mood and irritability.

When to see a doctor

Because these feelings have gone on for such a long time, you may think they'll always be part of your life. But if you have any symptoms of persistent depressive disorder, seek medical help.

Talk to your primary care doctor about your symptoms. Or seek help directly from a mental health professional. If you're reluctant to see a mental health professional, reach out to someone else who may be able to help guide you to treatment, whether it's a friend or loved one, a teacher, a faith leader, or someone else you trust.

If you think you may hurt yourself or attempt suicide, call 911 or your local emergency number immediately.
