(((MommaR))) Please don't stress about how the house looks, it will be ok. You and daughter both need low stress. I've had so many of these people come to my house, and looking back I can see how stressed out I would get before hand. And then that spreads to the whole family feels it too.

My son once screamed at the cps lady... "Get away from me you fat old b****"
Another time he locked himself in his room, many other times he broke things right in front of them.

Our situations are not the same, but I so feel for you, wish I could help. Just try to keep things calm, don't worry about material messes right now. Let your daughter be the focus, not the house mess, not the therapist. And taking care of you too. Hope hubby is giving you lots of hugs.
