Titanic Sails Off!

We had our first music rehearsal for Titanic last night, and I'm feeling a bit overwhelmed. The music is really challenging (even for the people who do this sort of thing all the time). All of the sudden I'm having a sinking (no pun intended) feeling about this whole thing (a little too late, I know). I'm just thinking about all of the rehearsals I will have to miss, and realizing (after seeing the music) that I can't really afford to miss them. I didn't thoroughly think through what a time commitment this would be when I auditioned. For instance, tonight I have aerobics, which I will have to leave early to go to praise band practice, which I will have to leave early to go to Titanic practice! Not to mention I am completely swamped at work (May is referred to as "hell month" at Hit Trophy). I didn't know anyone there, but I'm sure I'll get to know people in time. Plus, the style of music is SO different than I am used to singing. The musical director even called it "borderline opera." Not exactly praise and worship. I'm sure the big picture is just scary and it won't be so bad, but for now the sentiment is...YIKES!
