How'd it go? I like the idea of just hopping on the treadmill and doing a quick walk. Are you sure it's self-pity and not just plain sad or something else? I know that my instant reaction is to be hard on myself sometimes. I read something that said that people do better with food when they're better at recognizing emotions than if they were taught nutrition and exercise info. For me it goes so much better with food when I'm feeling kind to myself and patient.
