No need to reply unless you just happen to pop in here - but did I misread and your appt. isn't until Monday?
If that's the case - as far as I'm concerned - it's "The Weekend" and your MIL, husband's aunt and your husand will just have to take up the slack. It might not be perfect, and you might feel a bit funny - but I think it's really important that you just rest up, and put yourself first.
I don't know if this helps at all, but I do a ton of cooking, cleaning, all kinds of stuff during the week, but when the weekend rolls around, it's almost like I go 'on strike'. It's not that I'm purposely dropping everything - it's just that I have other work to do on weekends, and my husband steps in and takes over and does all of the cooking, basic cleaning and errands.
Don't laugh, but last summer when my Mom was quite sick with a serious health issue, I was up there helping - and I ended up literally ordering my stepdad to do the dishes. He did it.
Unfortunately, he did not know how to do dishes properly and somehow ended up putting regular dish detergent in the dishwasher instead of the proper dishwasher soap...hilarious!
All of a sudden, there were mountains of foamy suds coming out of the dishwasher and onto the floor. Thing is? He was *determined* to do his part. I guess I'm just saying that husbands/Dads do come through. Even people who don't know how or who try to kind of escape the whole thing - they can and will come through if you insist.
My stepdad was very glad to be able to help - he jumped right in and did the dishes, the laundry, asked me what groceries to get and so on. Started cooking and trying out recipes. He wanted and needed to feel useful, especially when his wife (my Mom) was sick. He learned how to do a whole bunch of stuff and I'm convinced that this made him feel a thousand times more effective at managing the crisis at the time.
I guess I'm just saying that it's not a bad thing to rely on others, even if it's not the norm. I strongly suspect that your family (your husband's aunt, your MIL and your husband) would *love* to help and feel useful. It's just that we all get stuck in our routines and habits, and sometimes people feel funny stepping outside their usual role/routine. Having said that, I still maintain that everyone really and truly wants to help. You just have to give them the chance, the opportunity.
Sometimes, you have to ask.
Ask for help. It might be that there will be soap suds all over the kitchen floor and you might have a burned grilled cheese sandwich delivered to your room, but it's a *good thing* for everyone involved. Sometimes people just don't know what to do when everything's gone haywire, and yet - they do want to help out.
Just some (probably burned and ruined) food for thought.
Hang in there!
PS - editing to add: I hope I'm not saying too much here, but in my experience, sometimes people feel a bit panicky and even a little bit paralyzed when things go wrong. Nobody wants to step up for fear of saying the wrong thing, making the wrong move, or possibly stepping on someone's toes.
I can pretty much promise you that if you ask - you will be pleasantly (and even humourously) surprised. Your loved ones will step up and take care of you. It may be that they just don't quite know what to 'do' in the situation, and don't want to do the wrong thing.
Having said that, be prepared for some really great times - and some fun stories to reflect on later when you feel better. I'm *still* teasing my stepdad about the time he put regular Palmolive dish detergent in the dishwasher. He was all alarmed about it at the time, but in the end, it lightened up everyone's mood.
