My dad is in the very last stages of terminal brain cancer which is a secondary from his lung. He is very, very quiet... no radio, no tv, .... eats very, very little and drinks hardly anything... sleeping 20 hours out of 24. I worry about him being scared of death and I wonder whether he is still capable of thinking about such things. He just stares into space. Can anyone advise please? I think he's in his very last few days.
