Depression - Cause
Depression is a disease. It is not caused by personal weakness and is not a character flaw. When you have depression, chemicals in your brain called neurotransmitters are out of balance.
Most experts believe a combination of family history (your genes) and stressful life events may cause depression.
Some people say they drink alcohol to "drown their sorrows" after a bad breakup, job loss, or other major life stress. Alcohol does have a sedative effect on the brain. A few beers or glasses of wine can seem to relieve anxiety and make you feel more relaxed and calm. A drink once in a while when you are feeling stressed out or blue is one thing, but using alcohol as a way to deal with your problems could be a sign of alcohol abuse. Drinking heavily might also be an indication that you're depressed...

- Genes: Your chance of having a bout of depression is greater if other family members have had depression. You may have inherited a trait that makes you more likely to get depressed. If this is true for you, a stressful life event is more likely to trigger depression.
- Life events: Stressful life events can trigger depression. For
example, you could become depressed if you have:
- Lost a loved one.
- Had a baby (depression after childbirth).
- Recently divorced.
- Been diagnosed with a long-term (chronic) disease such as diabetes or heart disease.
Sometimes even happy life events, such as a marriage or promotion, can trigger depression because of the stress that comes with change.
Just because you have a family member with depression or have stressful life events doesn't mean you'll get depression. You also may get depression without going through a stressful event.
Other causes
Health problems also can cause depression. For example, both anemia and an underactive thyroid gland (hypothyroidism) can lead to depression. Treating the health problem usually cures the depression.
Certain medicines, such as steroids or narcotics, can cause depression. If you stop using the medicine, the depression may go away.
