Two months after her husband's death, Connie was still not herself. She often forgot to feed the dog, was late for work on a regular basis, and had not yet taken his clothes out of the closet. Which of the following diagnoses could apply to Connie according to the DSM-5?

The correct answer is: major depressive disorder.

Explanation:

Major depressive disorder, commonly known as depression, is a mental condition that is characterized by continuous internal pain, low mood, low self-esteem and loss of interest in activities that were enjoyable before.

This disorder can be heavily discapacitating as it can interfere in normal life and work-life as well, while also producing abnormal eating and sleeping habits.

Connie has lost her husband a few months ago and she is not recovering from the pain that it caused her, which makes her deeply unhappy, not interested in anything and incapable of performing common tasks on her daily life. These are all symptoms of depression.
