Oh, lots of hugs! I don't think any of those things are stupid.
If it were me, first thing tomorrow I'd call the salon and ask if there's *any* way you can get in before Friday - a cancellation, or maybe your stylist would be willing to come in a bit early or stay a bit late to accommodate you? Because you want to feel good about yourself and it's going to be a while before you're up to going out and doing that after baby arrives!
Then I'd get my bag packed, including going out and getting my new PJs. Or if you can order them with two-day shipping from somewhere, do that with your feet up! (While drinking your water!)
Unless there's something specific you wanted to make ahead for food, I'd just lay in a bunch of boxes of pasta and/or some fast & easy things like taco makings. We didn't really freeze anything ahead, and it was OK. We might not have eaten any three-course gourmet meals, but between DH and I we managed to make enough reasonable dinners to not be ordering pizza every night.
And then when your DH gets home from work tomorrow, have him set up the bassinet and Rock-n-Play. If necessary, pull out the tears and/or pregasaurus.
In the meantime, I'll keep my fingers crossed that you'll get your extra week!
