No, it is not necessarily true that people who sing a lot are unknowingly depressed. Singing, like any form of creative expression, can be a way for people to cope with their emotions, including those related to depression. It can be an outlet for emotions and a source of joy for many individuals.
However, it's essential to remember that singing or engaging in any creative activity does not necessarily indicate depression or any other mental health condition. People sing for various reasons, such as enjoyment, passion for music, or simply because they find it fun and fulfilling.
Depression is a complex mental health issue that can manifest in various ways, and not everyone who sings or engages in creative activities is experiencing depression. If you or someone you know is showing signs of depression or struggling with their mental health, it's essential to encourage them to seek professional help from a mental health expert or counselor who can provide appropriate support and guidance.
