What is major or clinical depression?
Major depressive disorder (MDD) is a condition characterized by signs and symptoms that interfere with the ability to work, sleep, eat, and enjoy once pleasurable activities.

To be considered major depression:
Your symptoms aren't due to a mixed episode – simultaneous mania and depression that can occur in bipolar disorder
Symptoms must be severe enough to cause noticeable problems in day-to-day activities, such as work, school, social activities or relationships with others
Symptoms are not due to the direct effects of something else, such as drug abuse, taking a medication or having a medical condition such as hypothyroidism
Symptoms are not caused by grieving, such as temporary sadness after the loss of a loved one
Although major depression is a serious mental disorder that profoundly affects an individual's quality of life. It is highly treatable. Many types of treatment are available. Medications and psychotherapy are very effective for most people. Some studies have shown that antidepressant drug therapy combined with psychotherapy has better results than either therapy alone.
Selective serotonin re-uptake inhibitors (SSRIs)
Serotonin and norepinephrine reuptake inhibitors (SNRIs)
Norepinephrine and dopamine reuptake inhibitors (NDRIs)
Monoamine oxidase inhibitors
There are several types of psychotherapy that have been shown to be effective for depression including cognitive-behavioral therapy (CBT) and interpersonal therapy (IPT).
Cognitive-behavioral therapy (CBT) helps to identify negative beliefs and behaviors and replace them with healthy, positive ones.
Interpersonal therapy (IPT) focuses on the interpersonal context and on building interpersonal skills.
