Harvey, if you don't have any of his possessions try something the American Indians used to do(and still do for that matter). Make a medicine pouch.
Whatever you have of him, a button, a piece of cloth, anything - you could even take a found stone that catches your eye and consecrate it with a prayer about him and use it - then put these items in your medicine pouch. When you have all the items you want(not too many)in your pouch, then consecrate the medicine pouch with a prayer.
If you want to make one, go to a leather store like Tandy Leather or get it online and pick up a piece of soft leather(roughout, both sides is best for this purpose). Make a template out of cardboard in the shape of a small 'drawstring pouch' then cut and sew the leather to make the pouch. You can add a longer drawstring if you want to wear it around your neck.
Or you can just buy the pouch already made.
Heres a place

Just another idea to help you get through these tough times.
Hope this helps.
