she's made the choice to go back, head held high, and confront it head on. in any situation like this it's ultimately going to come down to how she gets her autonomy back so she can move on. she's already made the vital first step by going back into the class, so the best thing you can do for her now is to back her up and support her decisions. doing things for her or on her behalf isn't going to help her get that autonomy, and trying to 'protect' her isn't, either.
if you like, feel free to drop me an email - i have some contacts i can get in touch with that might help if you feel like you want something outside of what you're already getting from the school.
