Hard Decision's To Make

My mom called me tonight and said the renal doctor came in with an update. He said basically there is nothing they can do to help my dad at this point. He said the renal damage has been caused by my dad's high blood pressure over the years and I assume with the recent chemo it has really brought this to light. He said he is not a candidate for dialysis yet but possibly in the future. So at this point they said we really need to make some decisions about what we want to do in the future. Do we or do we not continue Chemo and let the cancer take its course. They are talking about letting me dad out of the hospital tomorrow. This is just to much. I mean how do you sit down with your loved one and ask them if they are ready to die?
