Mdoodles, arent you moving out of your house anyway? To sell it? Maybe then the proper advice would be to NOT pack his things, but get on the stick packing yours.
But if thats not the case, I would at least get some boxes. Maybe you can start by taking his movies out of the DVD case, or his books, or coffee cup. Start small. When you dont have traces of him everywhere to make you think of him, you will feel better.
I guess I gave the wrong finger to the wrong man...
