Post partum preeclampsia - Day 3 in hospital - need some success stories, depressed.

I was fine all along throughout the pregnancy except I had placenta calcification which was being monitored from 30 weeks. OB decided we give birth as calcification was getting worse. Baby girl came through at 38w6d via csection weighing 8 lbs 7 oz. On the day we were discharged to go home, later that night I started having trouble breathing while sleeping even if I propped up my pillows. I rushed to ER, BP was 181/99. Super high. They injected me and gave me some medication. In the morning, I was still not feeling better so I went back to hospital and I was admitted. On admission, they did all tests; liver, kidney, fbc etc and all were fine except kidneys. Urine proteins, high creatinine levels, uric acid etc. So definitely preeclampsia which is affecting my kidneys. Nephrologist says I’m not a candidate for dialysis as yet so not so sure what he means. Currently hooked up on three blood pressure meds and it seems to be going down but my kidney function is still not improving. Has anyone gone through this, particularly post partum preeclampsia with acute kidney failure . What was your experience ? And how soon were you out of hospital? How are you now? Did you get pregnant after that?
