Oh, dear....I'm so sorry. I can only just begin to imagine what a punch in the stomach this must feel like.
I am sure there are some practical things you will be able to do, and others will be along soon who have more experience. What I hope you know is that not all of these problems need to be solved right now--this minute. Please try to get some rest yourself this evening and begin to tackle all of this in the morning.
There is no shame in asking for help when you need it
