What would happen to a person if he discovered that everything he believed in turned out to be a sham?

There was a book out years ago called something like "when the opposite of everything you believed is true". I think it depends on what we grew up around but most of what we learned is wrong....I believed death was a horrible thing & learned it was just our society...we will say "I am sorry" I had to make my own card for someone whose son died because the cards were all sympathy cards...I wrote something about knowing it is all in perfect divine right order...we all are going to die so why should we act like it is so shocking? I had a 20 year old son that died & it taught me more than most people will ever learn in their life time...I thought parents were supposed to die before their kids. That is such a harmful belief. I have another son & we are so close because I don't treat him as if he is going to outlive me. We appreicate each moment...I actaully have made a career at helping people to look at what they believe & see if they want to keep that belief or get rid of it & maybe replace it with a better belief. So I could write a book on all the garbage people carry around in their minds. ...So what would happen is they might resist change at first but after they see things getting better they would love it...I started out as a personal organizer. Then & I loved it. People at times became emotional when they had to get rid of something they held on to for a long time. Then I wanted to work at home so I started working just on the mind not the physical manifestations of the mind...It is such a rewarding experience....Cleaning the clutter out from the mind can be hard to do for a person on their own but it can be done. I help people by holding them accountable to get it done. I also help them through the emotions that come up but this shows they are really healing. So it can be very hard especially if someone faces this discovery on their own but it they can get through it is the most rewarding thing they will do.
