How old are your children? Even the youngest of them can help you with things, and the older kids can help bathe the youngest, while you supervise everything and instruct them. Things may not get done exactly how they should, but it'll be good enough for now

PLEASE don't hurt yourself any further

And see if the pharmacy can deliver your meds, a lot of them will.
Who will take care of the kids if you have to go back into surgery? Let the house go for now, just make sure everyone is fed and reasonably clean. your health is top priority right now and your children would be so proud to help take care of mommy. I know, I've been there with 4 young boys when I had my daughter by c-section

My stepson's mother thoughtfully dropped off DH's three boys as soon as I got home from the hospital and my DH had to work the next day. I already had my 7 yo son with me. They were from 6 - 9 years old at that time and were the biggest helpers! YES, the house was a wreck, but it wasn't disgustingly filthy, and we all helped each other through it. Sandwiches and soups are easy and not too messy to clean up after. Paper and plastic EVERYTHING is your friend.
I'm so worried about you and I wish I was closer, I'd be there in a heartbeat to help you out
