Forgotten you were moving house, Winnie. What a lot to cope with.
I had this too - we moved house days after I heard my mother had a terminal illness, with a life expectancy of two months. I was functioning on a practical level but was numb on another. I had no wish to make our new house homely beyond the unpacking. My husband helped me/made me go through the motions, to help our son (and us) feel at home, and give me something else to think about. I felt guilty for enjoying the odd moment, depressed at the futility of it and angry that I was having to do this right now. Though I realised it would have been even worse to face a house full of unpacked boxes day after day. Making any decision, even the smallest ones took ages, and my memory and concentration were shot to pieces.
In retrospect, I would have got in cleaners to help make the house tidy and functional, and then put off every single decision possible.
Moving into our home meant there was a big something else going on in my son's life, which I am sure helped him to cope with the awful family situation we were all thrown into. Winnie, I hope your daugher can take some comfort from the move.
My thoughts are with you.
