Have you tried journaling? I did that when our son died and then forgot about it....came across it yesterday and was really suprised at some of the things I'd written.

When our 8 yr.old grandson died I wrote him a letter that first Christmas and told him how much we missed him. His mom put it in his stocking. It's hard to look at those empty dinning chairs.

If his family doesn't want to come, have a dinner party for church friends...people who would also be alone. Hugs.
