I'm glad you're back too! Sounds like a tough couple of weeks.
Don't worry about being out of your environment when you get a regular job. I have myself a hefty sized insulated lunch bag and I load it up with all my "stuff" from home. You plan ahead and devise yourself a nice plan and you most certainly CAN make healthy eating happen - where ever you may be. Routine is good. You'll see.
Oh and no need to crawl back. You did fabulous with those 2 weeks by not gaining. No need to crawl back even if you gained.
