Hope, I thought of a goal for your future new house.
You could decorate it all over - this would take you weeks, would be something you can get your DD's involved with, is a distraction and at the end of it, your new house will look great, be all 'yours' and things you wanted and it'll feel like a home then.
That's what I did when I moved out of the marital home. My place was so run down it wasn't fit to live in and it took over a year just to fix all the problems (which I was glad about as it was something to do) and another 2 months to decorate.
I had a new kitchen put in, new carpets, curtains etc, and bought quite a bit of new furniture (I had to because he took half of it). Now when I walk into my house, it's this burst of colour and everyone loves it - I have numerous comments from people.
It would be something D11 would probably enjoy helping with and you would feel so proud afterwards, it might ease the pain a bit.
