I've also had tons of work to do, and I find that exhausting as well. It's been stressful and I'm just now starting to feel human again.
I'm here for a conference, and all meals are provided, so I brought no food with me. I also eat with tons of people (there are as many chairs in the place we eat as there are participants, so you never need to worry about sitting alone.) and that makes me self conscious about what I'm eating. I avoid eating lots of carbs in general, but they don't have tons of protein, so it's usually just some veggies and a protein that's probably fried. A lot of the veggies seem to be cooked in tons of oil, so I avoid them, and everything's pretty salty so I try to load up on the fresh veggies instead.

I also haven't weight myself since I got here. I'm a weigh-myself-every-10-minutes kind of person. I've been writing down what I'm eating, but not having a scale (like weighing my food in front of colleagues is a better option) and not knowing what's in my food means everything is up in the air really. When I left I weighed 156 and my 10 day average was 157. I go back and forth between "I feel like I'm not eating anything, I better have lost weight!" and "I'm only eating crap and I'm barely moving, I hope I didn't gain anything!" Which leads to my question to start asking people:
HOW DO YOU ONLY WEIGH YOURSELF ONCE A WEEK?!?!
Doesn't this drive you crazy? Goodness.
