Major depressive disorder, also called major depression, is characterized by a combination of symptoms that interfere with a person's ability to work, sleep, study, eat, and enjoy once–pleasurable activities. Major depression is disabling and prevents a person from functioning normally. An episode of major depression may occur only once in a person's lifetime, but more often, it recurs throughout a person's life.

Q. I like to know the signs of serious major depression in women? I am lecturer in a college who is very approachable to students. If you take the top 10 lectures in the college the students will vote me first. Though I am proud of it I am not jealous. One of the clubs chose me as the best lecturer of the year and wanted me to send to another country for a special training in their own expense. Now I am here in this training which lasts for 6 more months. First week I fell home sick without seeing my students and got depressed and moreover I could not CONCENTRATE in the training and COULD NOT SLEEP. I like to know the signs of serious major depression in women?

A. If I wish if I am a student then I like to get trained under you. I am jealous of your students. The symptoms of depression in women are the same as those for major depression.
Common complaints include:
• Depressed mood Loss of interest or pleasure in activities you used to enjoy
• Feelings of guilt, hopelessness and worthlessness
• Suicidal thoughts or recurrent thoughts of death
• Sleep disturbance (sleeping more or sleeping less)
• Appetite and weight changes
• Difficulty concentrating
• Lack of energy and fatigue
