Hey, you can do it!
So you ate a little?
Seems carby. Were you restricting? (generally- i believe you're calorie counting, and most calorie counters do restrict carbs, not on purpose, but you know...carbs give you the least bang for your quantity of food buck). whatever, it happens.
Bright side? Go workout, you're going to have a killer workout. I always have my best times/endurances/most strength after a carb-load, because really? All you did was carb-load....nothing more nothing less.
