I cheated...

So yesterday my grandpa was admitted into the hospital for Congestive hear failure. I have a weird way of showing I am nervous or stressed...I either A)Make selfish remarks or just seem like I don't care or B) eat...and guess what I did...BOTH! Not to mention last week I was PMS'ing (TMI) and I was on eating overload...so the weekend , had a weak end. 
I cheated on my diet...I ate EVERYTHING!  I'm human and I get this week is a new week, which by the looks, I wont be able to weigh in until Sunday. So with that said, Any words of encouragement, because I feel really bad about NOT dieting yesterday However, in an article "Cheating on your diet to increase fat loss" on Calorie Count (Click on the link to read the article) it says cheating one day to boost yourself from a plateau (which I am at since I didn't gain or lose last week) one must cheat or UP their calories and it's proven to work...so HOPEFULLY this is what I need.
