Flour + Sugar Can Suck It

For the past, oh, three weeks I've been trying to start F.A. over again. For those of you who have been following my food blog since the beginning, you'll remember it's a program in which I weigh and measure my meals and avoid flour and sugar. It's very specific, and the rules are black and white. It's probably one of the hardest things I've ever done, but it works and is so worth the effort. So what's the problem? I left back in February and haven't successfully done this program since. These past three weeks are the closest I've gotten. I feel like I'm at a mental stand-still and need something to push me. One would think my wedding gown would be reason enough.
It's funny because the sponsor I'm currently working with has given me a food plan with plenty of food; I'm literally never hungry. This food plan, however, is way different than the one I used to lose weight for those first eight months. I kind of want to go back to that food plan; it's familiar and I know it works. I'm not sure how I'll lose weight with the amount of food she's given me now.
This program asks that I simply do what my sponsor asks me to do, but if any of you struggle with addiction or not having control, then you should know what I mean. I want to give up and just trust what she says, but I'm having a hard time giving in. I guess I still want to do it my way. I need to remind myself that doing it my way got me nearly 30 pounds heavier since I left program last winter.
I know that I'll do this; the majority of me wants to do this. It's the miniscule fraction of me that's putting up a fight, and to be frank, it's getting on my nerves. I know I have to this program together because Thanksgiving is just around the corner, and there's no way I'll make it through the day without eating if I don't get this program solidly planted in my daily routine.
I read today, "If you're making mistakes, it means you're trying." It made me feel good, even briefly. I've identified the problem and I'm working on it, however I'm struggling.
Words of advice and encouragement are always welcome!
P.S. I'm going to try to update this blog more regularly, but we all know how that goes.
