Hey 6strngs_2hmbkrs,

Stick with it, just remember your are there to worship god, he knows what your playing. I have kind of a similar situation. I can play heavy stuff all day long and fairly well. But now... instead of playing Slayer and or Deicide type songs, I play with the childrens worship band at my church. Its a little frustrating because now I have to read music and play chords other than plain or bar chords, and instead of just flying up and down the neck I have to really think about what i'm playing and be tasteful. It has been a HUGE positive in my guitar playing but is so stressful when Im fumbling with m7 and 9 chords and figuring out what to play over top of them. The other guitar player (who is a theory head and a great player) told me "just keep working on it, your playing to worship and God hears you. And when I look out and see little kids singing and dancing around it makes me stick with it.

Hope that helps a little.
