I spent yesterday evening and all day today helping out, cleaning up the house, arranging details, driving places, etc. Also just trying to be supportive, be available. It's been a hard and sad couple of days for me, but I know it's nothing compared to what my friend is going through.
Reminds me vividly of all that happened when S died. At least I can hopefully make this a little easier on my friend, since I know some of the trauma and difficulties I went though then. I know what are the hard things to do, and I know how much easier it is for somebody less intimately involved to take care of them, so I'm stepping in and doing as much of that as possible.
Also spending a lot of time praying for all involved, and a lot of time hugging when I can't think of anything else to say.
