As for me, I only share my health conditions with my very closest friends. I prefer to be private about such matters. I would never post on social media or talk about it with strangers, except for my Mayo Clinic support group folks who are in the same boat as I.
Furthermore, I do not allow my health conditions define who I am. If a close friend turns away, know that person was not a true friend. As Paramahansa Yogananda so wisely said, "Loyalty begins where convenience ends." Those willing to go through the ups and downs of life are the ones you want to keep...and share with. Just my two cents!
