Dear overtherainbow,
First of all, YES! Newsies all the way. Second, these girls don't sound like the kind of people whose opinions you should care about. Theater people can be super mean, believe me I know it, but try to see past these cruel people. Some people get a kick out of judging others, and it's awful. But you've done nothing to them to cause this kind of thing. Talk to your REAL friends about it, and try to rise above their pettiness. Rest assured, you are much a much better and stronger person than any of them ever will be. Don't ever let them get to you.

PS We have very similar taste! My favorite book is also The Book Thief and I ADORE Next To Normal (Robert J. Spencer is wonderful...). In fact, my situation is almost the same (smart girls cyberbullying and messing with me in my theater program). We should talk sometime, even if it's just about musicals ^_^ PM me. :)
