Diagnosed 2 Days Ago

@raich As has been said - who you tell is totally up to you.  However, it might be good to let some people know so that if you need support, they are aware of what is going on.  For me, my kids go to the school I am at but I was just "on leave" to most of the students - my kid's friends were aware though.  My colleague's all knew but I left the telling to the co-ordinator.  I only told two friends and asked them to pass on the news to others.  I also told people that I didn't want them calling me to talk about it but as time went on, that mattered less.  I also kept a blog with updates on progress and gave family, friends and colleagues the address - this has now become a sort of diary of that year.  I have never felt that I needed to keep the news to myself but I did want to control how and when I spoke about it.

In the end, it's whatever makes life easier for you.
