Awwwww...don't worry. We all have days like that from time to time.
You said yourself, you did BETTER than you would have in the past.
"...chicken, bacon, olives, and pepperoni. I also didn't drink any of the soda, but I wanted to."
See? Look at that! Your habits have already changed! Imagine how much worse you would feel today if you had eaten the way you used to! But you didn't. That's a victory in my book!
Get back on the wagon today...and be prepared for the next time. When your husband brings pizza, bread sticks, and soda home next time, try to be even stronger. It's okay to eat pizza. You just have to learn how to do it in a healthy way.
