Because of the world or our society, the way we live, people can be come depressed. People can get the blues as they say. People can become unhappy with their faith, if they had any, and turn away from God. You can become more worldly or humanistic rather than spiritual. The more worldly we become and the more we look to man and turn away from God, the more pain you will have, because we continue on in wrong thinking, wrong ideals and wrong hopes. If you don't have wisdom, which is God you can make the right choices.
