frustrated beyond belief

So this week I have been trying to get my diet back on track yet I know it has not been a good week. I weighed in today just to see where I was at and I am down to 147. I should be happy that I have gone from 151 to 147 because it means that I have lost 2 pounds a week yet, I have a feeling tomorrow will be a rough weigh in because while my eating has been ok I did let myself eat graham crackers with icing. Please pray that this week I am able to get my diet back on track and stay on track.
