Throughout the course of our lives, we all experience episodes of unhappiness, sadness, or grief precipitated by unexpected events like failure in exams, rejection by loved one, death of a close one, personal tragedy or difficulty such as divorce, loss of a job, etc and may feel depressed (some people call this "the blues"). Most of us are able to cope with these and other types of stressful events. Over a period of days or weeks, majority of us are able to return to our normal activities. This is called Normal Reactive Depression.

Normal Reactive Depression is different from Medical Depressive Illness.

Normal Reactive Depression requires no treatment. Just assurances, supportive empathy and encouragement would be useful. It does not affect day to day activities and routine life. People bounce back within a few days.

Medical Depressive Illness is not a normal variation of mood. The symptoms of this disease last for weeks and months and the person suffers a lot affecting their regular pattern of living.It is the illness in the brian's nerve circuits that affects or changes our thoughts, moods, behavior, activity, attitude, habits and personality from what we normally are. Some neurotransmitters like Serotonin, Norepinephrine and Dopamine are less in quantity in some parts of the brain leading to dysfunction of the brain's neural circuits. 

If one has depressive disease, they are often unable to perform daily activities as before. They may not care enough to get out of bed or get dressed, much less work, do errands, or socialize. During this phase, the depressive illness fluctuates with few normal days of functioning and mood. One may feel better on few days of the week but then the depressive symptoms prevail on most days and gradually the number of days of depressive illness increases.
