y-pod,
I'm really sorry to read what you are going through and I can appreciate how shocked, confused and frightened you must be especially at this time of year. I agree with the other posters who recommend that you go to see your father as soon as you can, if that's at all possible.
I experienced something very similar because my father passed away from cancer several years ago. He was in hospital beginning December 5th. My mother was in denial and she continued working, cleaning for Christmas, decorating the house etc., rather than visiting him because she sincerely believed he would get better. She expected to have a hospital bed set up at home for Christmas so that he could join the family even for one day. People deal with their emotions differently and there's no right or wrong way. My mother avoided the hospital whereas I sat with my father, day in and day out until the end.
My father passed away on Christmas Eve and my mother feels a lot of regret that she wasn't there. I don't just mean 'at the very end', I mean in the weeks prior when he was able to communicate a bit. Like your mother, my mother had absolutely no clue about finances, etc. It was an arduous long road for my brother and me to teach her, and we got her a financial advisor as well.
I share this story just so you know that I feel for you. If you'd like to PM me please do.
Hugs and prayers at this tough time.
Isabella
