Hi,
I think we all do whatever we need to. I dont think its over top. Despite not really being a facebooker i invited more people as a friend and just wrote about my experience. The advantage of limiting people to my mind allowed me to be unfiltered. I have overseas relatives so they could follow along. I made the decision that it was my journey and i used it as an opportunity to record what was going on. I can go back and remember certain things now which has been useful. I also posted other crafts and things i was working on to break it up. Some people found the topics (even baldness) a little confronting so i tried to post happy stuff occasionally.
