I'm partial to the litany against fear. Not super deep, but I can say I've recited it quietly to myself a few times! It's a decent tool to acknowledge, process, then repress and move past true fear.
I must not fear. Fear is the mind-killer. Fear is the little-death that brings total obliteration. I will face my fear. I will permit it to pass over me and through me. And when it has gone past, I will turn the inner eye to see its path. Where the fear has gone there will be nothing. Only I will remain
