I have a relaxation / guided imagery called "Clear the Deck" that's on a CD called Natural Tranquilizers that talks about putting your worries and concerns of the day into a sturdy box... with a lid... and a lock with a key that you can put in your pocket... and know that you can take these concerns out later any time you wish.

I don't know how putting it in a box would work in your situation, but this guided imagery works well to give a kind of burden-lifting relief, a reprieve from carrying the worries and concerns for a while.
