You're in despair my friend, go out for a walk and start doing yoga. Listen to music that makes you feel good and watch movies that make you laugh. Yoga for dummies with Sara Ivanhoe is a great first yoga dvd.
Jobs that are easiest to get? Fast food, foor server, department stores, pizza driver, taxi driver. I've known PHD's and commodity brokers that did these things temporarily during personal/financial crisis, it's not failure, it's being strong and coping with your immediate challenges. Good luck to you!!
