I suppose the better question would be what am I not afraid of?
Am I afraid of this all encompassing, "follow you off the edge of the world" feeling? Of course. I've had it and lost it before. I am terrified of risking that again.
Am I afraid of making the wrong decision? Certainly. A lot hinges on my ability to do the right thing and I'm no longer even certain what that is.
Am I afraid of losing my sense of security? Yes. I've come to value security a great deal and no longer find myself in a position to throw caution to the winds.
I am afraid to breathe, to move a muscle. So instead I hide until some of that fear subsides.
