How do I balance chemo risks with kidney disease concerns?

So it's been a little ruff. One week, my immune system was basically at 0, so I isolated myself to go back on Tuesday find out praise God my immune system came up so they gave me treatment for me to then be called in saying my kidney number skyrocket I also have stage 4 polycystic kidney disease so they said i was dehydrated and gave me fluids. They said I had uti and gave an antibiotic I had never taken before. I was cautious and called to verify I was to take cancer. The doctor said yes. No sooner do I get off the phone. My kidney doctor calls telling me to go straight to hospital they are admitting me for renal failure. They were going to start dialysis but praise God my kidneys reached to the fluids, and my numbers came down for the cancer doctor later to call asking how many of the antibiotics have i taken and to stop them when I let him know I had been admitted to the hospital which he later showed up to tell me take a week off to get my strength back up and we will start Tuesday the 12th back up with where we left off. I really am worried the same thing is going to happen all over again, but this next time, my kidneys won't hold up. Is it wrong to stop chemo . Is it being too selfish. No one ever told me what my outcome would be if I didnt take chemo but the symptoms have gone from just the 9 weeks of chemo I have had. Just needing some thoughts here lost at what to do
