Crushed, again

Sometimes I just don't understand people and the choices they make. I realize that life is complex but there are basic right and wrong choices. Maybe there is no wrong anymore. I'm tired of living in a world populated by egocentric people who only do what makes them happy. Also, we are only worth how much we support or make someone else feel happy. Otherwise, we are completely worthless and cast off as such. What is this world we live in? I think it would do people good to revist morality and ethics and to remember that the world doesn't revolve around them and the decisions they make. I don't want to be a disposable person anymore.
