Suz is right, Ally.
If you can look at this time as your time to learn how to say no to difficult child's demands, and as a time for difficult child to learn correct priorities, the experience will be a more positive one for both of you, I think. difficult child will bargain with you, manipulate you and the situation, if she can. She would love to re-establish those ties with her old friends. That way, she can count the days until she can pick up her old life and habits, again.
The other thing I would ask you to think about is that now is the time when it is safe for YOU to bring up old issues. Try to see difficult child's home visits as rehearsals for when difficult child comes home for good. You will expect that the rules you have set up for her will be obeyed. Let the conflict come now, while she is in a safe place for those issues to be addressed.
Use this time while difficult child is away to plan how you want your family to function when she returns Ally, and face every issue head on BEFORE difficult child is released.
When there was trouble in our family, I took that message that I had created the situation so much to heart that I could not stand up as a parent. The kids, especially when they are in trouble, need us to be strong. Looking back on it now, that is the problem with bad treatment centers ~ they destroy the parent's belief in his or her own capacity to parent correctly, and the troubled child is left lurching from pillar to post. Kids need strong guidelines. If you were driving across a very long, very high bridge without guardrails, you would be frightened. Same thing with the kids, I think. They have gone a way we never expected and so, we find ourselves without a clue as to how to cope, how to help them.
Try to set up that clear path for your daughter now Ally, before she comes home.
And this time, you have the Board to help you know which way to go, and to give you strength when you just aren't sure anymore.
