Good thread!
Things I do for self-support:
Prayer & Bible reading (actually Holy Spirit support )
Read (I have a huge collection of books)
Visit the library
Play with/groom/walk/talk to my 3 wonderful dogs
Computer time
Call a friend just to talk (not about problems)
Watch a TV show I've DVR'd
Retail therapy doesn't usually work for me, as I am on a strict budget right now

but I know it helps a couple of my friends.
