Depression is more than just feeling sad or blue. It is a common but serious mood disorder that needs treatment. It causes severe symptoms that affect how you feel, think, and handle daily activities, such as sleeping, eating, and working. When you have depression, you have trouble with daily life for weeks at a time.
Back to Clinical depression. There's no single cause of depression. It can occur for a variety of reasons and it has many different triggers. People often talk about a "downward spiral" of events that leads to depression. If someone in your family has had depression in the past, such as a parent or sister or brother, it's more likely that you'll also develop it. The hormonal and physical changes, as well as the added responsibility of a new life, can lead to postnatal depression.
Depression is a mood disorder that causes a persistent feeling of sadness and loss of interest. Also called major depressive disorder or clinical depression, it affects how you feel, think and behave and can lead to a variety of emotional and physical problems. You may have trouble doing normal day-to-day activities, and sometimes you may feel as if life isn't worth living.
Sadness, feeling down, and having a loss of interest or pleasure in daily activities are familiar feelings for all of us. But if they persist and affect our lives substantially, the issue may be depression. It can affect adults, adolescents, and children.
