Have you been taking measurements? because you should start.
There's research posted on the maintainer's forum I think about how people create a 'mental' image of themselves that sticks. It's very common to not see yourself differently. I went from 170 to 210 and saw a bit of difference, but barely, just like I'd gained 5 pounds. Then I lost it again (and went from a 22 to a 14) and it took me a full year to 'See' myself thinner. I kept on seeing myself at the weight I was used to.
Biology backs this up, in fact, when you look at how the brain works.
so that's how I fight it. I can look, week by week, at how I've been getting smaller. Today I went from a mile to running a mile and a half and felt great.
I think you need other things than numbers to concentrate on. If it was me (because I've started down that neurotic thing before) I would talk to people, which you've done by coming here, and then put the scale away until after thanksgiving. Are you trying to fit into a size for your vacation? Or do you just like the number?
It sounds like maybe (and totally ignore me if I'm wrong) a dose of 'your number IS NOT YOU' is in order.

You are your personality, lifestyle, habits, etc.....you don't become a better person by the second digit of your weight being a different number. No one will give you a million dollars for it. The world will not become a better place. It is the changes you're making in your life, like eating better, exercising, taking care of yourself well, that make YOU a better person.
SO: Keep your cheat day. ENJOY it. Enjoy yourself and the people you spend thanksgiving with. Then on friday, keep on going like you have been. Because trust me. Listening to that voice only tells it that it's worth listening to. It will never stop if you pause to feed it, not without a hammer and a blow torch.

Don't feel guilty about turning down food, but stick to your calorie goals or food plan or whatever.
My aunt is quite large, and she's very proud that she's constantly only eaten a bagel and a coke that day-when it's 3 in the afternoon. She is totally convinced that eating less means weighing less. If that was the case, wouldn't it be a breeze to lose weight? Wouldn't she be thinner?
No. That voice in your head is the voice of perfection. tell it to back off, and if it persists, beat it over the proverbial head with a two by four.
