Thanks to everyone for their kind words.
I just picked her up at the rehab and we had a good conversation on the way back. She feels awful about this. They told her to reapply and it looks like they may take her back in a few days! Except for the smoking, they really liked her there, but they had to do something after she had broken the smoking rules so many times. She was also very depressed because she had lost several day passes due to smoking.
She very much wants to go back to rehab, either this one, or someplace new. I believe it would be a mistake for her to go back to this one because smoking would still be a problem even though it is very good in so many other ways.
