Stress=Slim down

There have been many times I heard or read about how stress will make you slim down, took off a bit of your weight, bla bla bla.....It's kinda bullshit. Now I'm in the tension state but I didn't find any of my weight run away from me. Or....probably I have not reach the minimum tension level yet. It doesn't help that I am so lazy to exercise since the day I completed my pre-wedding shoots. I used to go either swimming or gym 3 times a week and look marvelous in my wedding gown. But now I feel bloated. There's no way I can slim down in just 5 days. I'm only praying that I will get so tension and scares some weight away.
