Depression is a mental health condition which causes you to feel unusually sad, listless and hopeless. It can be triggered by a specific event, like the loss of a loved one. It can also occur spontaneously due to no specific external factor; for people to whom this applies, the cause may be biological, meaning their family members are also likely to have depression.
Depression can affect your social life and your work life. It can also make you feel unmotivated to do anything to improve your health, so you will be less likely to seek treatment if it gets too bad.
At some point in their life, many people will experience depression. For some people, it will eventually go away on its own. For others, aggressive treatment in a professional setting may be necessary. Cognitive behavioral therapy (CBT) is a good and often reliable method for treating depression. Drug therapy is also used with CBT for some people who have depression that does not respond to traditional therapy alone.
There are several kinds of depression, which can be mild, moderate or severe. To learn more about depression and how it works, follow the link here to watch a short and informative video.
