Falling behind

And 121 again. I was doing so well I was down to 118 and then I got excited and started eating like crap again. Today included. I ran a 10k this morning. Which is great yes, but afterwards I ate 2 pieces of french toast and then for dinner I had 2 pieces of pizza (home made with fat free cheese and lots of tomato sauce) and, this is the worst part, not 1 but 2 cinnabons. At least 1500 cals for the day. I need to feel motivated again. Anyone want to do an ABC or some kind of competition?? Please, I need some help here!
