Step-by-step 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.
