Help - newly diagnosed with breast cancer

I am so afraid and unsure of what will happen to me and I want still to live my life.  My Mum had breast cancer and I can't help thinking of her and how she suffered.  I know it was a long time ago and things have improved, but I have nobody to talk to as my family live far away and my husband does not hear very well and seems not to want to talk about things anyway.  I feel alone.
