I suppose you could say that if you fear something, then there must be uncertainty as to whether or not you'll beat whatever it is (because if there was no chance you wouldn't be afraid, you'd be resigned to it - in the same way that terminal patients are generally unafraid of death, whereas someone who isn't terminal but has severe injuries may be very afraid). Therefore the fact that you fear it is actually a positive thing because it means you also have hope. And focusing on the hope should make you feel less afraid.
