Depression is feeling sad, blue, unhappy, or down in the dumps. Most people feel this way once in a while.
Major depression is a mood disorder. It occurs when feelings of sadness, loss, anger, or frustration get in the way of your life over a long period of time. It also changes how your body works.
Causes
Health care providers do not know the exact causes of depression. It is believed that chemical changes in the brain are responsible. This may be due to a problem with your genes. Or it may be triggered by certain stressful events. More likely, it is a combination of both.
Some types of depression run in families. Other types occur even if you have no family history of the illness. Anyone can develop depression, including children and teens .

Symptoms
Depression can change or distort the way you see yourself, your life, and those around you.
With depression, you often see everything in a negative way. It is hard for you to imagine that a problem or situation can be solved in a positive way.
Symptoms of depression can include:
- Agitation, restlessness, and irritability, and anger
- Becoming withdrawn or isolated
- Fatigue and lack of energy
- Feeling hopeless, helpless, worthless, guilty and self-hate
- Loss of interest or pleasure in activities that were once enjoyed
- Sudden change in appetite, often with weight gain or loss
- Thoughts of death or suicide
- Trouble concentrating
- Trouble sleeping or sleeping too much
Depression in teens may be harder to recognize. Problems with school, behavior, or alcohol or drug use can all be signs.
If depression is very severe, you may have hallucinations and delusions (false beliefs). This condition is called depression with psychotic features.
Hallucinations
Hallucinations involve sensing things such as visions, sounds, or smells that seem real but are not. These things are created by the mind.
Exams and Tests
Your provider will ask about your medical history and symptoms. Your answers can help your provider diagnose depression and determine how severe it may be.
Blood and urine tests may be done to rule out other medical conditions that have symptoms similar to depression.
Treatment
Depression can be treated. Treatment typically includes medicines, with or without talk therapy.
If you are thinking about suicide or are very depressed and cannot function, you may need to be treated in a hospital.
After you have been on treatment, if you feel your symptoms are getting worse, talk with your provider. Your treatment plan may need to be changed.
MEDICINES
Antidepressants are medicines used to treat depression. They work by bringing back the chemicals in your brain to the right levels. This helps relieve your symptoms.
If you have delusions or hallucinations, your provider may prescribe additional medicines.
Tell your provider about any other medicines you take. Some medicines can change the way antidepressants work in your body.
Allow your medicine time to work. It may take a few weeks before you feel better. Keep taking your medicine as instructed. DO NOT stop taking it or change the amount (dosage) you are taking without talking to your provider. Ask your provider about possible side effects, and what to do if you have any.
DO NOT stop taking it or change the amo...

If you feel your medicine is not working, tell your provider. The medicine or its dosage may need to be changed. DO NOT stop taking medicines on your own.
WARNING
Children, teens, and young adults should be watched closely for suicidal behavior. This is especially true during the first few months after starting medicines for depression.
Women being treated for depression who are pregnant or thinking about becoming pregnant should not stop taking antidepressants without first talking to their provider.
Beware of natural remedies such as St. John's wort. This is an herb sold without a prescription. It may help some people with mild depression. But it can change the way other medicines work in your body, including antidepressants. Talk to your provider before trying this herb.
TALK THERAPY
Talk therapy is counseling to talk about your feelings and thoughts, and help you learn how to deal with them.
Types of talk therapy include:
- Cognitive behavioral therapy teaches you how to fight off negative thoughts. You learn how to become more aware of your symptoms and how to spot things that make your depression worse. You are also taught problem-solving skills.
- Psychotherapy can help you understand the issues that may be behind your thoughts and feelings.
- At group therapy, you share with others who have problems like yours. Your therapist or provider can tell you more about group therapy.
