Of course your overwhelmed, and replaying this in your mind is normal because your trying to process it. I hope u can talk to your BIL because he was there and witnessed a lot of it, plus has his own experience to share. You went from speed of 150 down to 50, let yourself adjust. I know 7 days isnt a lot, maybe they offer additional support services, something he can do to bridge the therapy sessions? Christmas will be different, but you and the kids can still celebrate, maybe save some gifts for after he comes home but open some on Christmas Eve or Christmas day as usual. It will work out.
