I am really sorry that you have been thru so much with her and it is clear how hard you tried to help her ! I hope she comes to realize just how much you did do for her, and will come around. I think her going to live with them might be the best thing ....at least for you and the rest of your family. Take time after sh has gone to rest, decompress, and know in your heart you did ALL that you could do for her ! She was lucky to have been raised by you, and some day, she will realize that.
