To conquer fear first we must understand that fear is actually the fear of loss, we are afraid to lose something, right?
The way around this is to realise that nothing was ours to begin with, we didn't bring it into existence, nor do we control it. Give everything back to God, by saying "I give it back to you, it was never mine to begin with. I give it back to you and I submit to your will what you wish to do with it. I submit, I submit, I submit...". Once you do this and truly accept it then fear can't touch you
