my father has terminal bladder cancer

I am my father's caregiver and he has terminal bladder cancer.  He has given up and is under no medical care.  He is depleting quickly.  We live in Houston and I wish I could locate someone who can tell me what to expect as he nears his end.  All he does now is sleep, eats very little, and is in lots of pain.  Any suggestions are appreciated.  God bless all who are on this site!
