Answer:
Depression is both a mental disorder and a feeling of extreme desolation and numbness.
The mental disorder causes you to feel that life is a pointless endeavor and cease to expect happiness and satisfaction out of it. People and friends get pushed away and it causes you to sink deeper in as you forget what makes you happy.
Many people self-diagnose depression for attention or sympathy. The fact is widely recognized, so those with diagnosed depression may not reach out for help for fear of being called out as an attention seeker. Just something i'd like to point out, it's a problem less addressed.
