Good, hard exercise to burn off the stress.
Work ahead on your classes so when recruitment is over and you are exhausted, you will have given yourself a bit of a cushion.
Do whatever you can do to relax and not think about it. Watch favorite comedies, etc. Give your mind and body a break in whatever fun ways you can.
And not everyone may think like this, but think through the worst thing that can happen and make peace with it now. Sometimes facing your fear head on (not getting a bid) and knowing that you will be okay with it eliminates some of the stress and pressure.
