Tick, Tick, Tick.... 

I have never experienced what you are, but I am sure it has to be a very sad thing indeed. I know my being the one to leave at his request, taking nothing with me but a suitcase and important documents, it felt very weird to just have so little to unpack, lonely is closest I can come to that feeling.
     I think making as many changes as possible would be a good thing, painting, move the furniture to where you like it, finding more fun and exciting pictures to hang, out with the old, in with the new!
{{{HUGS}}} wishing you happiness in the new beginnings... ; )

It is sad. I felt sadness with each memory that I packed up and sent to my ex. But it also made me angry that I was once again doing the packing. In his sense of importance or shame he couldn't even get his things out of the house. But it still was sad.

Start making the house yours. Change the furniture around. Change up the rooms. I've been known to make the living room the dining room if it fits my needs. Will it hurt while you are making those changes. Hell yes, but it will be so much better for you than keeping old memories around.
