This is deja vu' for me and DS..............
I know exactly what you are going thru.....you know we went thru this about 6 years ago, but at least DS was able to be with his dad when he died and, thank God, they had a good relationship.
If you need ANYTHING, advice on how to handle things, which direction to go, or just to talk, you can contact me ANYTIME. E-mail me and we can exchange phone numbers, if that's easier for you. Whatever is most comfortable to you. In fact, if Jake needs to talk to someone who's 'been there', I can put him in touch with Chris. He's going to school in Laramie right now, but will be home for a week this coming Sat.
PLEASE let me know if you need anything and you and your family are in my prayers.........
