You don't need to right this second. You are spinning and rightly so. I'd recommend sleeping on it. Respond when emotions aren't so high.
Hugs.
I think CC has it right, here. I know this whole ordeal has put a damper on the holiday, but nothing is going to happen in the next several days that will be helped by fretting over all the details now.
Please take a step back for at least a couple days and try to be kind to yourself. You're doing all you can, and I think you've done quite well - even though it won't seem so to you until you can look back on it from a calmer time. Don't panic, just let the situation have some time to level out.
