I know how you feel. When I was in high school and in the band, I played the tenor saxophone, but because my parent's didn't have a lot of money, I was borrowing my cousin's. One day, she announced she would need it back because she had sold it. I was livid! I had been scheduled to go to a band camp to play the saxophone and my flute in a concert, and she didn't even warn me. I still went and just played my flute. I got over it eventually.
