On June 1st, I found out I was
in stage 5
renal failure. I found out, after going to the doctor to find out why I was so sick. I had extreme fatigue, slept constantly, had no appetite, was weak and numb all over, could not concentrate or remember anything, so My guess is, if you have the same symptoms I did, (which are common with kidney failure) you won't be able to keep it a secret when you reach stage 5 and you will probably be glad to go on dialysis by then.
