I learned last week that my father is in the hospital and will be there a while, so I'm planning to fly out next week. He's not critical, but it may be time to start talking about nursing homes. He's not pleasant to deal with, but it has to be taken care of.
I think seeing your dad is a good idea. It's better not to look back and possibly regret not going. I'm going through some family hassles too, but I know this will probably be the last time I will see him due to the distance and expense.
Let us know how things go for you. Take care.
