Stressed out

All day today (and last night too, for that matter) people around me have been telling me to calm down and that all will be fine.
Why?
Because the finance most likely won't be ready tomorrow which means we need to ask for an extension. H and I are freaking out big-time! Mortgage broker said "don't worry, it happens all the time". So did the lawyers. And everyone at work, and the real estate agent.
But you know me. I always stress.
Almost vomited twice at work today too. No, not a very good day.
