Hi, Im so sorry to hear this is happening, I really hope that CPS does get involved so you guys can all work together to keep the kids safe. It looks like you made this post this morning so I assume you have told them by now and called CPS. How did it go?
I also want to give you this website a friend of mine uses....I hope this is appropriate on this board, but as far as dealing with a minor with an eating disorder, there is a wonderful way to get support for the caregiver (which is you for now)

Good luck to everyone in the situation. I'm so sorry to hear about it and will keep everyone in my prayers. Keep us updated, okay?
