Organ failure i don't believe?

Hi i have been told that my mum is dying of organ failure and only has weeks to live. the Macmillan nurses have moved her into her bungalow with no carpets or decorating as this is where my mum wants to be but i have been told not to spend money on the house as i will need it for the funeral but she looks fine and acts fine what things do i need to look for as i am having real problems believing this as i was told she had hours to live 2 years ago because of a bleed.
