Mila, I think detachment is a process that takes time, at least for most of us. It's a hard thing to do when you've been M as long as we have and cruisin down the highway of life and then all the sudden have to spike the brakes and do a 180. It's no wonder we hit a brick wall sometimes.
There are times my H still gets to me although it is less frequent now and I seem to move past it a little faster than I did before.
It really is no wonder that piecing would be the hardest thing to do in this whole ordeal. After so long trying to block those feelings it would be very hard to get the walls down that have been built up to protect us.
Have a great weekend and good luck with whatever you decide about the yard work.
