Hi, I'm like some ppl here. I don't post anything on my facebook and I don't announce it. My family members do know. My mother has told relatives who I didn't want anyone to know either, but mom told. At my work no one knows and I don't intend to say anything at least not yet. But my reason was for my diabetes, blood pressure, migraines, fibromyalgia to disappear in time. So far no more medications for diabetes nor blood pressure.
I believe its no one's business to know, but in time ppl will find out.
It's up to you if you are ready or not ready to tell anyone.
Good Luck to you!
