Back to school

It's back to life as usual. The kids are back to school today. I am very frustrated. I weighed myself today and I am up 2 pounds. I went off the plan one evening this week, just one evening, then back to perfect the last 2 days. I took my blood sugar this morning and it was high after no sugar all day yesterday!! When I was younger, all I had to do was give up soda and I'd lose weight...what is going on!!! The drama today is going to be staying on track even though my numbers are up. This has always been the struggle for me. I feel like, whats the point. I am sacrificing so much, for what!?!! If it is working, then great, it's all worth it. But if it isn't, then I just feel like an idiot!! I am going to try to stay positive today, and on track...God help me!!!
