What is the point I am missing?

The meaning of life is "I want". From the time of birth to the grave the human condition is and always will be I want. So what are you missing? You want but you won't admit it. You want all of the things that you listed however you have either been denied or feel that you want something different than what you got as a result your pissed off at the world. And to your question as to whether suicidal people were mentally ill. No I don't think there mentally ill i just think their terminally misguided.
