[ZenGum]

I'd say, in a somewhat Buddhist* manner, that you are very enlightened. It is the craving for personal immortality that drives most of the suffering in the world. Let go of the desire to live forever, and you are free of the fear of death.
Equally, Epicureans* would agree that there is nothing to be feared about death and non-existence. Before death arrives, it isn't here for you to worry about, and after death arrives, you aren't here to experience it. It is only the actual event of dying that might be accompanied by some troublesome pain.
I go with both of these viewpoints. And someone around here has a signature much the same, which I am too lazy to search for. So even if you are a nutter, you're not alone.

*Many modern varieties of Buddhism and Epicureanism do not hold this. I think they've missed the point.
