I'm wigging out here!

So yeah...first off..sorry for my extended absence...I was involved in many a project this summer...(notice ommision of tawdry details)
anyway, i need your sage advice once again.
so yeah. possibly the biggest audition of my life is coming up on monday. I'm freaking out in a major way. I have my song (okay I've had it for 8 months) but i don't know what else I can do to prepare besides practicing and resting my voice.
I'm freaking out...help!
