Coming Back to the Program

I am coming back to the program. I had great success on the program up until about a year ago. I was able to lose 40 pounds through moderate exercise, counting calories and making healthy choices. The loss took about 2 years total. However, this past year has seen 20 pounds gained. Between the normal day-to-day challenges of two kids running all over the place, I have also been facing emotional stress. I am about to turn 38, I have gone back to college, I changed jobs six months ago, and recently suffered the loss of a loved one. Needless to say, my life has been in turmoil, so I should be thankful that it is only 20! I am looking for encouragement and motivation to stay the course even though life sometimes gets in the way.
