Other people just don't get what a new diagnosis feels like. I have no real wise words but when you feel stong enough call his parents. Tell them you feel awful for not speaking with them at Christmas but you were in an emotional mess, you love them and care for them and need their support as this journey is not only difficult for you but will be very difficult on their son. Hope it works out.
I set up a private facebook page and invited people in. It photographed my journey and I journalled my thoughts, feelings and fears. I included this article which is brilliant. Whilst you are just beginning your fight, it gives valuable insight into thoughts and feelings.
Thinking of you. Kath x
