Hey, if you're going for a route that could kill ya, and that's your primary fear, yet you want to do it anyway, then you gotta accept your own death:
Imagine yourself dead, in a coffin, and marinate on that for a bit. Marinate on it 'til you got no more fear. If you can't get to a place of no fear, then keep on marinatin' 'til you do. Seriously. You have to be comfortable with the possibility of your own death to be able to enjoy the climbing at all- otherwise you're just Twighting out there, trying to slay your dragons of self-worthlessness.
And if you can't accept the possibility of your own death, then running or golf are absolutely fine alternatives, ones that can be enjoyed by sane and happy people.
