Proceed with confidence and positivity. You didn't get 3 kids without being a strong person.
The first thing I'd do is call a family meeting and use proactive listening. This is YOUR time and they need to know that for a few weeks, you're going to be "on vacation."
Put necessities on counters and tables so you can get to them without bending, reaching or lifting. Sort out your meds and supplements so you don't have to have that added concern. In the ramp-up to surgery, make sure they know IT'S YOUR TURN, and they need to put you first.
It's really such a short time. I had an open procedure with a 7" vertical incision. I was at an outdoor gathering two days after I got home. I couldn't eat or play but I had a lot of conversation with friends, then went back to bed.
Prep meals and freeze them. Keep takeout menus and grocery delivery services on hand in case you need more help.
You can order what you need online and get it dropped at your door.
So relax and make sure you put your recovery first. Believe me, it's over way too soon!
