Hi there .. venting is good .. get it off your chest ... most of us have a vent day too ... but if it were me ...a hug , a hand to hold, an ear to listen, and just being there when needed ... Chrissie x

Chrissie is right; say what you are feeling.  Everyone here will understand the need to vent.

Talk to your family member; find out what she would like you to do.  Remember she is still the same human being as she was before her diagnosis.  I have helped care for a few cancer patients and a recurring theme was that they did not want to be handled with kid gloves all the time.  Is care for her children assured if she doesn't make it?  Does she want to talk about that?  Sometimes you have to just feel your way through and listen to any clues she gives on how she wants you to relate to her.

Hope you come back here to vent.  Annie
