addressing the morning after election night

Something about my sinful nature has to be addressed this morning, because last night I did nothtbut go against all that I know about nutrition. It made sense in the beginning... use up my old white sugar and white flour in a couple baked treats to share with my friends (half of whom are guys and have faster metabolisms, right? Or who eat that junk anyway... right?) Anyway, I knew I wouldn't be touching it. The popcorn would take care of me. And if I did nibble on something, well, I'm starting a diet- so I shouldn't feel too bad. Well, after a couple cookies, two pieces of cake, lotsa popcorn, and a bowl of chex mix, I was disappointed in myself. It just seemed like the old failures rising up again. Phrases like, "Ha, nice self-control you've got there" and "good luck with your diet :P" tend to haunt me after these times. And I fear losing control again. WHY?
