Many people think that depression means being sad and blue, but the symptoms can be quite different. Take our assessment quiz to find out if you might be depressed. Recovery doesn't happen overnight, but therapy, antidepressant drugs, or a combination can end your suffering. A major depression is generally acute and short-lived, while mild depression may last for years.
Scientists believe depression is linked to genetics and brain chemistry.
You may also be more vulnerable to depression after a breakup, divorce, or other major loss, or if you've experienced sexual or physical abuse, a parent's alcoholism, or other trauma.
