A fate worse than death

Basically to assume that living a really long life is horrible and dangerous. Let's say that you were currently alive and something extremely unpleasant has happened to you that would possibly result in mental scars. Something so bad that it will stick with you for the rest of your life and you just can't wait for death. Death is an absolutely natural part of life. You're gonna die at some point so you might as well accept it while you still can. Sometimes it would be much better for most people who really have it worse than others.
