Answer:
Withdrawal.
Step-by-step explanation:
Depression can be defined as a mood disorder or mental health illness which is typically characterized by feelings of sadness, low self-worth, loss of interest, guilt and pleasure.
This ultimately implies that, an individual who is depressed becomes gloomy, down-spirited, withdrawal, loss of appetite, and interest in what they usually find pleasurable before that mental state.
Hence, depression tends to motivate withdrawal behavior and a highly introverted feeling. Thus, depressed patients would more often than not stay in isolation or stay alone without relating with anyone.
