I feel the same way about not deserving to eat because I'm unhappy with my size. But I know not eating does more harm than good with weight loss - slowing metabolism and upping the urges to binge. It's so hard because you can't just go cold turkey as with alcohol or smoking or one particular food item (i.e. chocolate).
But I've been working very hard on not verbally abusing myself because for as long as I've been doing it (decades) it has not been producing any positive results. And it's emotionally draining. I've been trying to be really conscious about when the food stops tasting as fantastic as the first few bites....realizing that might mean I'm full and packing the rest up for later. I'm trying to sort out what's conscious eating and what's rationalization. Do I need to eat something at 1am after having a decent dinner? Probably not. Cup of tea to the rescue. It's like a friend of mine said to me "Nobody NEEDS fettucini alfredo" - and I realized that craving specific foods is an emotional craving, not what my body is telling me.
It would be kind of sad to not have any of your mom's cooking during the holiday (or feel stressed out while trying to enjoy them). Can you make a plan to pack some portions up to freeze, so that if you stick to small amounts of the carbs, you can keep doling them out to yourself over next month or two? Food and family issues are tough! I got the "you shouldn't eat that" combined with the "let's go get carrot cake" type combination most of my life. It's no wonder my brain is a virtual battle ground! You have to do what's good for you. Tell that mean voice in your head to butt-out and try to conjure up your inner yoga-instructor. Honor the body, don't punish it. 8)
