Stephanie,
I've been through this with both my parents and my father-in-law. You know your Dad and family are in all of our prayers, and I, for one, don't have many moments go by in the day when I don't think about him. Do all you can do and know that it's in God's hands, and he'll hold yours as well. If you need a sounding board, you've got the site, and you've got my number. Don't hesitate. We've all been in this together for a long time.
Shoofly
