Deepest condolences for you in your time of grief.
I know what you mean about your mom being your Dad's world. It's awfully hard when the person you've been caring for is no longer there. Does he have activities he could pick up and do, that would take him out of the house - friends his age that have activities he would like to join them in?
I hope things are as well as they can be, for him.
for your Dad as well.
