Hi again Dana
i was hoping someone else would have written tonite to add more ideas
i am thinking that your dad is probably struggling with this serious diagnoses and is going to be going through a lot in his body and mind.
i am going to suggest that you keep on with the calls, the offers, bring by food, stop in for coffee, or biting tidbits of favorite dishes, just keep the communication open.
knowing you are there will be of great help to your dad - it all takes time, to process diagnosis, treatment etc.
i have a family member my age who has been dealing with colon cancer, and has taken chemo for a year.
although we are not close, I started a private Facebook group for the family, friends and anyone who wanted to send daiily or weekly messages, post photos, jokes, just say that we were thinking about her.
it turned out to be the best thing I could have done. Now that may not work or be suitable for your dad - but it's an idea.
i hope that this might give you an idea of something you can do for your dad that is just for him, that makes him feel the attention and thought that you so obviously have for him
I realize we are all different, and it is different strokes for different folks. Just continue to do what you are doing, make every day count, every visit. I know you already do.
i also understand that it's not every child who can handle parents - it's not easy to turn the tables and take care of them. It's alien, it's hard to accept.
hope this helps, sending you a hug, look forward to hearing what you come up with that works.
Fear is a big thing, fear of losing health, fear of pain, the unknown, so just handle with care and patience:)
good luck. And remember, you take care of you. It's hard to be the caregiver too.
best wishes
