What Is Depression?
Let's begin with some facts about depression:
Depression is not the same as feeling down or blue.
Depression is an illness that affects all aspects of the body: your mood, your thoughts, eating and sleeping, the way you feel about yourself and the way you think about things.
Depression is not a sign of personal weakness for which the person is to blame. People cannot just "get over" depression or "pull themselves together."
The Symptoms of Depression
Here are the symptoms of depression:
- feeling sad, blue or depressed most of the day
- losing interest in or pleasure from activities throughout the day
- losing or gaining weight without trying
- sleeping to much or an inability to sleep
- feelings of restlessness
- feeling fatigued or having no energy
- feeling very worthless or guilty
- trouble concentrating
- thoughts of harming or killing yourself
If you have experienced some or all of these symptoms nearly everyday
for at least two weeks, you may be suffering from depressive illness.
The Causes of Depression
What Causes Depression?
Scientists do not know exactly what causes depression, but we know that depression runs in families and may be partly genetic.
Genes may cause a person to have levels of certain brain chemicals that are abnormal and that may make a person vulnerable to experiencing depression.
Depression is also more common for people who have experienced very traumatic or stressful events in their lives, especially in childhood.
