There are two sides to this. I recently lost my father to cancer, and attempted to do what you are suggesting. There will be a limit to how much care you can provide being only one person. There is a team of people at the hospice that help things be more comfortable. Unless you get a lot of additional medical training, you won't be able to provide the medication usually given to people in hospice situations. The hospice life is all about making the patient comfortable as they pass. In my case, they gave my dad a butt load of pain medication and they were not trying to prolong his life at all. That's the bad side. People go to the hospice to die, and they help them along to it subtly. It was apparent that no one there was interested in prolonging his life. Make sure they are beyond return before you take them, but I am not sure if you can handle the last stages alone. It is extremely difficult. May God bless you all through this time. Take care.
