Oops, sorry I missed your post. I hope you've been ok. It is sooo hard to have a loved one suddenly gone. have you removed the picture thing?
I know my dad has a little shrine to his beloved Sheltie out in the garage. Every year he seems to miss Sparky a little less. So the pain does start to dull.
On really bad days I grab books and magazines and crawl into bed. Is that something you can do?
Going for a walk also helps.
