Well the only helpful thing that i can suggest is if you try to talk to all her alters, be supportive,listen,care,and give her lots of hugs. She needs to be able to trust you and know that you are there for her. She may have horrable storys and she will go threw a lot of pain. She might get headaches during the change. This is a very hard situation to handle. I hope you have the stregth and love that your gonna need to help her threw this. I have learned a lot here about it, my heart goes out to the both of you.
