Doing better than I feel

I lost 3.8lbs this week. That's a real good week. So why do I feel so fat today? Over the previous 2 weeks I gained a total of 5.2lbs and i didn't feel as bad as I do today. I think it will just force me to work harder so that's good. I need to get the other 1.4lbs off so i can start counting over. :)
