Okay! So, deep breaths... Ahhhhhh... that's right, innnn... and ouuuut...
The BEST thing you can do to help yourself right now is not to leave your meals and snacks up to chance. Yes, it's a mess. Yes, everything is new. My gosh, you might as well have landed on the moon! I completely understand, having moved several times in my life...
And of course, it has to be at this time of year.
So, as I said, get that food in order. Make sure that when you are hungry, tired, etc. there is something good for you to reach for. Something good, something that will nourish you and that you won't have to fuss over to get ready. Ideas: Cold cuts from the deli. Baby carrots and hummus. Heck, Lean Cuisines can be a real saver at times like this!
Drink water, don't forget that. Sometimes what we think is hunger is really thirst in disguise.
Get enough rest. I know, you're lol about that... but really! Rome or home, it's not going to be built in a day.
Sounds like you're doing good with the exercise--I'd say, much as your trainer would like to reduce your body fat, you put a hold on that plan until after things get more settled down at home. The thing you DON'T need right now is a new challenge, know what I mean?
Hang in there... be kind to yourself... don't worry... this will turn out OK.
