Hey Mom, I know it hurts when our kids hurt. She is not alone, rough recruitments happen, and it probably happened to other girls at her school. Just be a shoulder to cry on and an ear to listen. From your posts, that sounds like what you're doing.
Good luck to your daughter in her future endeavors in theater. From what I know from my friends' kids who are theater majors, it is rare for freshmen to be cast in productions, so perhaps she just has to pay some more dues to get a role...
As for dropping out of recruitment, I can understand how getting hit with the "double whammy" was just too much and she just couldn't pull herself together to pretend everything was peachy keen. Perhaps she can meet more girls, make some connections and try again.
It sounds like she's a great girl with a lot of interests, she will be fine in the long run.
