I went back to school and basically announced to a bunch of fellow cellists what had happened and showed them the envelope. Then I met with a new tutoring student, it went well, but I think I gave him some seriously weird vibes, I think i was very "focused and businessy" instead of my normal extremely relaxed math demeanor, but at least I didn't cry or anything, and I think he will become a regular client despite the timing.
Went back to school for a rehearsal, which went really really well. My cello sounds awesome. My ensemble was taking all kinds of risks that we never had before. Because we're communicating and supporting each other, the way we relate to each other is being transformed without having to talk about it. The energy and the feeling is fixing a lot of the "musical problems." Especially encouraging because yesterday was my first day back with my instrument after almost 3 weeks of no playing and I felt like I sucked a$$ but today I am feeling much better about myself.
