To be honest, as someone who has been badly hit by life many times, I find less and less things I'm scared of, and more and more things I'm just desperate or dissapointed or disgusted about. Not a good feeling really. I'd rather be scared and eager and hoping and expecting than sad, dissapointed or depressed.
Pick yourself up, life hits you hard. Pick yourself up again, life brings you down. I often get the thought that picking ourselves up after yet another fall is the main life task for most of us, dunno. God, what a horrifying thought

*hopefully it's just a temporary depression run*
