ehy dear @osmy07, I am very sorry for the loss of your father. your story is very sad because your father has suffered a lot in his life and we do not wish it on anyone, even if he was lucky to have a beautiful family like yours near! with so much love, which is the only thing that makes us feel a little better.
the opposite happened to me: my father died in a few days, without realizing it. he was put into a pharmacological coma and as they say he has not heard anything and has not suffered. this comforts me because I know how afraid he was of hospitals and pain. I miss him a lot, and this will never change. a big hug, I hope the best for you
