sorry to hear about your dad too sue ,  

my dad has been ill for over a year with acid reflux and being sick. not wanting to eat or drink alot because it makes him feel sick. actually i dont think we would know now if it hadnt been for my mum pushing for him to go for the camera down because hes lost over 3stone in less than a year.that was when we were told then he went for a mri scan to see how far it had spread a fortnight ago.like you with your dad i feel for him and at a loss what to do except be there for him and my mum.actually im glad they wont try operating or treating it as i think my dad would die quicker and suffer more as hes not strong enough .so now its quality time not quantity, he is struggling to sleep at night after nearly 60 years being with my mum hes is naturally concerned leaving her , so is trying to get things in order for her before hes too ill to be able to . i still find it sureal that he is going to die at some point in the near future but trying to stay positive and be happy especially around him offering support to him and my mum who is very good trying to keep him eating and drinking .
