Hi Michelle
reading your posts is like reliving all of mine from this exact time last year !! The not talking to family is very very common and i remember having the same discussion with Anne Marie when we both had this problem.
It would seem that while the effort will be made for "outsiders"
you are supposed to understand and accept how painful it is to talk,and not get upset by the fact that communication drops to practically non existent during this very very hard phase of treatment.It is one of the most distressing for a caregiver ,and tested me to the limits.
Like the rest of it michelle this too will pass,so keep your chin up.
love liz
