One thing that helped me is to let all your contacts and friends, family etc. know you're looking. I got a really neat job once by telling someone I sang with that I had gotten fired over the summer, and they were looking for a temp for a year or two.

Also, depending on your relationship with your credit card banks, you might want to contact them ASAP to let them know. This can be risky and backfire, and I would guess depends on your balance.

Good luck!
