Liz,
I'm so sorry for your loss; my thoughts and prayers are with you.
This past January marked the 27th anniversary of my father's passing, and I also get melancholy every anniversary.
I wish I had a way to take your pain away, but I don't. However, I'll leave you with a few words: The pain never goes away. You can move, get re-married, get a new job, whatever, but the pain never goes away. And that's a good thing. It's a good thing because it makes sure you won't forget, and you don't want to forget him, do you?
