(((((((Bebop))))))))),
Sending you love & prayers for God's strength to pour over you & help you walk through this most difficult time.
It's been 6 years since I was experiencing similar emotions with my Mother & there are times it feels like just yesterday. I know how difficult it is to be the one watching it all happen around you, so all out of our control......but the only thing we can control is what you are doing is spending the loving time with your Dad & enjoying the time you have with him, making it into good memories throughout the time.
May God care for you & keep you well & protect your father from any pain & suffering
