Thanks Jeff,
This is an epidemic, these people depress themselves subconsciously. They are stuck in the rabbit hole and have no clue where the exit is, much less know it exists.

This does not apply to people with real actual problems. Usually these unhappy people have no problems whatsoever which they cannot solve somehow. They usually don't listen and can't focus which is step one to shaking this off. It's a fine line for some and can be changed very quickly, but a few have no cure.

Most importantly, we need to love and care for each other if this world is to continue. We need to work hard to find out what that love and care actually is.

Most of these people are our family and friends, which makes it it extremely difficult to approach. And when engaged we cannot alienate or separate, it will make it worst. If you want to help you must set the scene for them, so they can see the light themselves.
