She had seven kids by the time she was 24 years old? Or she had seven kids over the span of 24 years? If she developed these issues through no fault of her own, I'd feel sorry for her. But she voluntarily chose to have seven kids and her health issues were caused by her serial breeding (or at least that's what she implies). It's like how I wouldn't feel sorry for someone who gets liver cancer after drinking their entire lives. You know it's gonna cause damage over time, yet you keep doing it.
Our bodies can take a surprising amount of abuse and can often recover completely or partially from a lot of shit. So when you body is completely FUBAR and shits the bed on you like this, you've pushed it way past its limits and probably won't be getting much of your usual function back. Seven loaves will do that to you.
Why do I suspect this woman was probably told five pregnancies ago that she's high-risk and any subsequent pregnancies will be dangerous or will cause major damage? We all know how much Moos like to think they know better than any doctor with their silly little medical degrees because Moos are black belts in Google-Fu and mommy intuition, so they go and do exactly what doctors tell them not to do because WTF do they know! Then they act shocked that what they were told would happen happens and say it was all worth it.
