You can get away from yourself. It's when you get away from yourself that you start to lose yourself. And it's when you lose yourself that you lose everyone else, too. So you're left with no one around you and a hole in the centre where you used to be.
And then you start to fall in.
When you cling to the edges and feel the wind whistling below you like the giant gaping bottomless pit in Star Wars that scared you shitless when you were a little kid, you somehow pull yourself back up again, and you start to remember why you loved being there in the first place.
