Welcome to the HealingWell Depression forum. I think Siobhan is right, it does sound like post natal depression. I am going to give you another site in case she wants to try it. It is a free online depression website.
I have heard many members say that it has helped them. I hope that it helps your daughter.
Please keep posting and let us know how things are going. I know that you don't want to enable your daughter and it sounds like you living there might be doing that, so I don't blame you for wanting to move out. But take care of you though all of this. It will help you to help her.
