So it's been a week since I started MFP. I've exercised so much and stayed within my calories. 3 days ago I found out I'd gained a pound, I had gotten to 159, then I was at 160. Today for my first official weigh in I did not think I'd lose, but I was hoping I would, but I didn't. I feel like giving up, feel really disappointed and like this will never work for me.

I bet everyone else has lost in their first week.
