Yes I had them do the same thing to me. I also had an abnormal mammogram and only told a few family members, because I did not want a lot of drama, and wouldn't you know it, I started getting emails on Facebook too from relatives I hadn't talked to in forever! I thought they meant well, I guess, but also intrusive since I personally had not told these people anything.
When I stopped drinking I also stopped logging into Facebook all the time. When I was drunk it was a bit of an obsession and man I sure did make a fool of myself sometimes. I realized when I sobered up that Facebook can really be a big stressor and I have never once regretted taking it off my phone. I will still log in occasionally to check on close friends and family but I don't even read all the status updates anymore, it stresses me out.
By the way, I hope everything turns out ok.
