Stress Eaters

I confess, I'm guilty of eating as a means to cope with stress. After a crazy day at work or at school I just want to throw myself on my futon with a stack of chocolate chip cookies and munch myself into oblivion. But it only makes me feel better for that instant when I'm stuffing my face. The guilt creeps in almost immediately, and my constant weight gain because of it is forcing me to find different ways to relieve my stress without food. I'm trying to wrap my mind around exercising when I'm stressed; everyone recommends it, but it's really hard to psych yourself up for a work-out when things are hectic in your life. Does anybody have any suggestions for psyching yourself up for a work-out during a stressful day? Or do you have another way you get over your stress without food?
