trouble getting derailed by stress

Stressful moments don't derail me as much as prolonged periods of stress. These past 3 months (this semester in graduate school) have been really stressful. I haven't lost a pound. I go up and go back down, but stay at or above the weight I began the semester with.

But for your situation, you should really turn to exercise. A good cardio workout that will really kick your butt. Endorphins release in your brain, giving you that same euphoric feeling that you get when you take that first bite of something delicious. Except, instead of punishing yourself with food for that sad feeling that you have, you're distracting yourself from that emotion with something healthy. I know it's harder to start a workout as opposed to grabbing a cheeseburger, but if you have the will power, the payoff is so much greater. And you won't feel guilty afterwards. You'll feel both proud of yourself and happy from the exercise. Give it a go!
