Hope today was not too horrendous for you - funerals are always bad, but much worse when someone is so young.
I am sure Honey will be fine - you have to leave her a lot longer overnight, and it is not as if you do it all the time?
We find if Buffy gets upset in her crate, Josie goes up and gives her a bit of a snuffle through the bars - their cages are next to each other - so I bet Mollie will do the same for Honey.
Have a takeaway when you get home, so you don't have to worry about cooking.
Hugs
