Do you know what your eGFR is? That is the percentage of function of your kidney. Talk to your Dr's and get their thoughts on preemptive kidney transplant. I know several people who have received a kidney before starting dialysis. I don't believe it is ever too early to look for a donor, and the search can take quite a while.
Watching your sodium intake is critical, and also watch your emotional health. Remember, we are here for you.
