Coly, I promise the stuff is just stuff. I saw the end and doom and gloom too. He still has stuff here. I was the one who ended up pushing most of it out the door. It really doesn't mean anything. Try not to give it any import.
It will be nice for you not to see it all the time and have the memories that come with it. Focus on the good memories, the happy ones. Focus on Coly and D what awesome things they are going to accomplish this year. Keep working on that detachment. When it comes, you will take the first breath you've taken in a long time and it will be lovely.
