DO WHAT MAKES YOU HAPPY!!!
If tracking your macros on Thanksgiving makes you happy, freaking do it! If it mitigates your anxiety, go for it! There's nothing wrong with that! Also, there's nothing wrong with NOT tracking! Unless you're deep in contest prep, one day of not tracking is not going to mess you up. Just do what you want and don't let anyone make you feel bad for it. BOOM. :)
I am not saying you should go balls to the wall eating everything in sight or have a binge-fest. If you've been tracking macros for a while, though, you probably have a pretty dang good idea of how much you should eat. So if you are not tracking, just eat mindfully and you'll be fine.
This Thanksgiving, I personally will not be tracking everything, but I will try to aim to hit my protein (estimating). Other than that, I'm going to eat mindfully and enjoy. I'm also probably going to lift on Thanksgiving because it makes me happy, not because I feel like it's necessary. Anyways, I just wanted to offer my $.02 on the matter. Much love and have a happy, stress-free Thanksgiving! <3
