Not much advice, but moral support. And a reminder to be patient.
I wouldn't ask her to do anything with her Facebook page. But you should feel free to do whatever you feel is right to yours. Including NOTHING, until your emotions are calming down a little. It seems to me you have more important things to attend to than her right now. I know this has been sudden and recent and you are disoriented. It's OK to feel that for a bit without having to do anything. Naming emotions is a way of calming them.
Best to you.
