Try to keep her thinking about other stuff (if possible). Is there any way that they can give her some anti-depressants while is is there? If you can, try to hire a sitter to sit with her, that way she will have someone to talk to and have company when you guys aren't able to be there. It makes a BIG difference!
Tell her that you and your family NEED her.
And tell her that everyone here on the.oRg is praying for her!!
