Yesterday (Thursday) when I walked in at work I got fired, how do I cope?

How to cope the day after being fired? I feel like such a loser AND my hubby isn't even talking to me! I took a long walk this morning and I am fighting depression from setting in. The worst part is the so called "church lady" in the office is the one who stabbed me in the back. She told my Supervisor that I called in to tell her what time I DECIDED I was going to be at work on Tuesday ( I was going to be a few minutes late and was just letting her know...) She twisted it and intoned that I was doing what I wanted to do with my work hours while my boss was off. How awful. This lady loved to brag how her husband is the head of so and so organization and how she does this and that at her church! I am crushed that she smeared me in such a way. Nice guys finish last always.
