A man walking in the night slipped and fell from a rocky path. Afraid he would fall down thousands of feet, because he knew that just at the edge of the path was a very deep valley, he grabbed hold of a branch that was overhanging the edge. In the darkness of night all he could see below him was a bottomless abyss. 
He shouted and his own shout was reflected back—there was nobody to hear him. You can imagine that man, and his whole night of torture. Every moment there was death below, his hands were becoming cold, he was losing his grip … but he managed to hold on, and as the sun came out he looked down … and he laughed! There was no abyss. Just six inches below his feet there was a rock ledge. He could have rested the whole night, slept well—the ledge was big enough—but instead, the whole night was a nightmare. From my own experience I can say to you: The fear is not more than six inches deep. Now it is up to you whether you want to go on clinging to the branch and turn your life free from that fictional fear.
