god, pls cure me!!

two days before my singing competition (final)...and now I'm having flu, sore throat and also coughing like hell right now...how am I suppose to sing for the competition? I'm very very worry about this..This competition means a lot to me...How? What should I do? Why do I have to face all these problems? I rejected to sing for Beethoven's night just because of this singing competition..And see what happen to me now? Pray for me...please...pray hard for me..I really gotta recover before my competition starts...God, please guide me throughout the competition...AMEN...
