Hope you're feeling better Readerbaby. Moving an office can be extremely stressful, and being sick on top of it just amplifies this.
I think you're taking on your boss's stress, and really, these are not your problems, they're hers. You are an employee, not the business owner. I know dealing with crabby rude people can bring you down if you let them, but again, it's not your problem. Just do what you can to the best of your ability and let the rest go.
Hang in there, you're almost free!!
