What happened?

Even though I walked with my dad most mornings, I gained weight over the summer. I started school weighing in at 217. The first few weeks of school were stressful as I adjusted to a classroom of 27 students, Bri going off to college, and driving my son to events he was involved in. I lost weight back down to 210. Been hanging around that weight since October. Now my schedule has been freed up, and I am ready to try again, for the 5th time to start taking better care of myself. I love my family and want my children to do and experience things and since I have such a large class, I find myself bringing a lot of school work home to do. I feel these are legitimate excuses for not exercising but poor food choices have no excuse. So here I go again.
