Hi Carol,
It's so much to deal with and there's plenty of people on this forum who can relate to the shock of it all. After the shock and all the initial information/tests etc, I did get quite angry - angry that this is going to have such an impact on my year. I felt like I just had to put so much on hold and also cancelled/postponed lots of other things. It has been 5 months since my initial diagnosis (had left mastectomy too) and am halfway through my chemo. And I still feel quite resentful at times that this is having such a huge impact. I don't want to be defined by my BC....but at the same time it is just the big thing happening right now.
Re. friends - I did find it easier to get some good friends to do the updates with others and let others know. Otherwise it is hard sometimes listening to other people's problems when they don't know what is happening in your life.
Sorry this isn't much advice but more a 'I know what you are going through'.
I don't know if you have a good GP but I think that's a good resource to use as a sounding board and to be the person that keeps an eye on the bigger picture - connecting all the specialists and having a more holistic view.
