Let me die now

So tonight the director of my Opera has arranged for me to meet the musicians she has found. They are "awesome", "Professional","Highly accomplished". Help. She wants me to meet with these guys and teach them my songs. Well that's not going to be very intimidating and daunting. Much.
I used to be a professional musician playing my chunky chunk crappy cover songs. I got paid good money too. But that was then. I have never been what anyone would call accomplished or virtuoso. I just had fun playing songs people wanted to hear and not very well.
So I have to teach these guys my songs.... why did I ever  start this? let me die now
