Nervous!

I am having a fit of nerves. I listened to the practice CD today and rather than it helping me understand my place in the music better, it made me nervous about playing this material. And they are bringing in a trombone player from Anchorage to double on the second part, so in essence I am just holding the place during our early rehearsals. I am surprising myself with how nervous I am all of a sudden. Where is this coming from?

I have to remind myself that in the last 16 days I have missed 9 days of practice, with all of my travel. So I need to go easy on myself. Ouch! We are such fragile beings!
