Thank you everyone! I am feeling much better.
Pregnancy broke my stomach muscles but it's fixable. Unfortunately the public health system has proven unhelpful, so after five unsuccessful attempts to find a surgeon willing/able to do the operation publicly, I will be enlisting a private surgeon. That will cost around $10,000 (surgeon + hospital + anaesthetist).
It is normal for stomach muscles to separate during pregnancy, and most women eventually heal (with a 1-2cm gap). I have a 9cm gap between my abdominal muscles, and an umbilical hernia. Those will both be fixed by the surgery (and yes, I will look much less pregnant—probably two months pregnant instead of six months pregnant), and it will also take some of the pressure off my damaged spine, feet, and uterus. Now that I officially have diabetes, my health is an urgent priority.

I am very grateful to all the kind hearts who have freely offered to help our family finally get this dealt with!
Update: The updated estimate of hospital costs have drastically hiked up the total amount we'll need to pay, since I will need to stay overnight and pay $5000. I can only assume this includes a gold-plated champagne bath and an on-call masseur (the second part may actually be true). I reluctantly concede that post-operative care is kinda useful and it might be nice to have people do a good job of it. And I bet the hospital food is AMAZING.
Update: The operation, anaesthetist, and two nights in the ICU are all PAID IN FULL thanks to you amazing people. I've had the operation and I'm starting to feel like myself again (but, you know, better!). Unfortunately I had a previously undiagnosed lung weakness (which explains part of why I was always tired and craving sugar) which has taken some physio to fix. That meant another three days in hospital, which is costing another $3270. My parents have very generously offered to pay (in addition to the huge amount they've already given me) but I hope we can ease the strain on them a bit by one last push.
