My dad has been terminally ill since November 2019

My dad has liver cancer, My dad seems to be getting worse, not controlling his bowels, sleeping alot, drooped mouth, always cold and getting confused. This seems to have all of a suddenly happened over the past 2-3 weeks. I don't know what to expect or what the signs for my dad getting extremely close to the day he grows his wings. I don't know how to cope with this. It's breaking my heart.
