Honestly, as if it's your "first time" it could be not as according as you planned and it's natural Rocky! -if i can call you Rocky?- But remember that next time you will be the one who encourages first timers!
Get your confidence triggered and Rock on Rockband!
How you manage to describe your fear i think you have overcome your fear of competition. This fear of confronting new things is natural and the only way to fight it is to go through it. I'd take my hat off to you when i see how honest you're with your self.
