At the very least, you can use this opportunity to educate your friends. You never know...one of them might have a family member who has CKD and doesn't know it, and the information you impart could save a life. I got a call one day from my husband's secretary; her husband had gone for his annual checkup and some of his labs hinted that he may have a kidney problem. She knew that I had CKD, so she called me up to find out more about what this number meant and what that number implied. I was able to help someone that day because I had been open about my renal problem in the past. Every day an opportunity presents itself to help someone in some small way.
I don't know if this will help or not,But when I told my family/friends I arranged for everyone to come over for dinner and sat them all down and told them..... I did not get much support from them (and still dont, they think b/c i go to dialysis that i am curred) but they asked me alot of questions and really all I can (or choose) to remember is that I was a hott mess with my crying..... This is still all new to me (diagnosed in september 2010).... but some days are good and others not so much... Just tell them and roll with it Good luck in your journey
