Throw in the Sweat Towel?

I felt like giving up this morning. Really, just throwing in the sweat towel. I had eaten more than half the days calories at breakfast. The scale is frozen & I felt like crap. I wondered if I should blog about it or what I should do. I decided to go to the motivation section & read until I found some of that motivation for myself. Read, I did, then I posted about all the non-scale victories on a message board, made a small, nutritious dinner & went to pilates. Someone offered me a ride home from pilates because it's raining. "No" I said, "I've already logged those 4 minutes." When I got home, of course, the dog needed a stretch. If I walked just 22 minutes more, I would be at 90 minutes for the day. I set the timer & off we went, returning in 22 minutes & 22 seconds. Now I'm feeling fantastic. What was the problem this morning?
I have been hovering at the minus 25 pounds point for about 3 months now. I have tried to be very committed this Fall challenge, but at times I have been very hungry. I'm not sure how to balance the increased exercise & my level of satiety. Right now, what I need is sleep.

By the way, when I subtracted my calories burned, from my caloric intake, I was barely over in spite of the crap breakfast.
