hey, focus on one thing at a time. Moving.
Now, if you want to improve the likelihood you will feel good doing it as well, then you are going to have to cut out the things that make you feel bad...I would get super specific, not follow anyone else's rules here. You have AS out, great, now does dairy make you feel bad? Does sugar make you feel bad? Cut out only the things that have a negative effect on your health. And for heavens sake, worry about your weight when your move in is complete, but not before.
For the sweet...put some chilled coconut milk and some fresh fruit into the blender, whirl and enjoy. Or pick something out on Dessertstalker or if it doesn't have and effect on you physically then allow yourself a cup of ice cream once in a while.
But, trying to drop all sorts of things in the middle of an unexpected move, not the best way to reduce stress, unless it reduces physical pain/discomfort.
