hey man i know what you mean the same thing happen'd to me when i broke my jaw
i thought ill be fine i don't really care ill be in to jumps straight away then was pretty etched but you just got to remember you used to do this stuff before and wouldn't think twice bout doing it then start out like you were learning but alot faster as in start small with 1s of little bumps and jumps then do 3s of little side booters and start just hitting jumps straight and then once your confident spinning again start spinning of the jumps and work your way up
worked for me at least now im all good even when i basically reenacted the crash which broke my jaw with out the breaking the jaw i was alright for the next run to try again
as some one said above its all mental soon as u break the first barrier they all fall
