My sister passed earlier this year, and I am finally finding time to go through her stuff (she had boxes of journals and old financial paperwork mixed with family photos). One of the trips down memory lane was from about 10 years ago, when she started having kidney problems. I had started thinking about what would happen if she asked me for a kidney. She was always really supportive of me, and helped me out a few times when things were bleak. But on the other hand, she would not take care of herself, or her body. Even when she became diabetic, she ate healthy for a month or two, and then went back to nothing but grease and sodas. And would eventually go days without checking blood sugar or injecting insulin. So while I felt like she would give me a kidney if the roles were reversed, I also felt like she wouldn't take good care of herself, and just end up needing a kidney again, and my sacrifice would be wasted. What do you all think - what would you have done in my shoes?
