Welcome and congratulations on your new wheels!
Will Rogers said, "Most men are about as happy as they make their minds up to be!" You were smart to rent before you pulled the trigger.
The best way I know to lower the stress is to make checklists. I have one for things to be done in the days ahead of a trip, another is a packing list, and another for departure. They prevent a lot of frustration!
I think we need to stop calling it "working from home" and start calling it "living at work!"
