I burrow down, let it sit and deal with it silently, I'm still not sure if I've gotten over the death of a close family friend a few years ago, I still expect to hear his voice on the other end of the phone when I pick up sometimes.
As for fear of death...well, I don't think I was born with it, I know you're naturally supposed to try and avoid death at all costs but I've often thought of my own demise and it never really bothered me. Perhaps it was the massive depression in my teens that had me let go of the fear, perhaps it's that I haven't really attached myself to anything 'worth' fearing death over yet, my responsibilities are limited and not all that many people depend on my existence, so I just don't see the point in worrying about it. Sure, my friends and family would be sad, but the most I can see coming of that would be they name a kid after me, but how sad is that? A constant reminder that your brother/friend died years and years ago walking around the living room? Nope, I'm pretty solid in my commitment to being burnt on my funeral pyre and being forgotten. I'd rather a celebration of life than a mourning of death.
