Mental health is such a complex thing and so difficult to diagnose. What is a mental problem? Who does have mental problems? What's the difference between mental problems and depression and sadness?
If you look at suicides most of them are connected to depression. And the mental health system just fails them. It's so sad. We know what to do. We just don't do it.
Depression isn't just being a bit sad. It's feeling nothing. It's not wanting to be alive anymore.
For my money insecurity depression etc can be healed by way of El Morocco sad songs at 4am and the pop of a champagne cork
