Told today mastectomy of my right breast

I have to have a CT tomorrow, a bone scan on Friday then back to the oncologist on Tuesday to find out what I need other than the right breast removed. I think I have been thru a range of moods today from silence on the 2 hr drive home to crying off and on. Luckily I have a wonderful husband he took control of my phone and rang our children my sister, sister in law, brother, mother, his mother and sister all the time telling them that " no she can't talk to you she is too upset " I could here the conversations and it was enough to start me crying when I heard them all say how much they loved me and what can they do . I have read a lot of stories where family and friends try to help but it get too much for person with cancer as newly diagnosed I'm going to set down rules from the start for my own sanity I love my family but I have always needed my space so I'll see how it goes
