This month has been 6 years for me too. I can relate with a lot of what you wrote. Those first few years, I could relive everything about those last two months when we found out the cancer was back to when he died. It was hard to push those thoughts out of my mind... now I have to actively call up those memories.(which I try not to do.) I still think about him all the time, but it doesn't hurt so much anymore. It's more of an emptiness that doesn't go away.
It's so weird how after all this time, you can still feel so in tune with others who have suffered this loss.
