I lost my fear of death years ago, when my ex boyfriend was constantly threatening to take my life. I finally had to get to the point to where I could tell him that if he did, then I could finally be rid of him once and for all. Don't think he liked that answer too much. But I just didn't care any more.
Personally, I'm kind of looking forward to when I can finally die. Death is easy. It's living that can be a pain in the rear sometimes
