I have gone off to motel rooms before to be alone. Nearly all motels have internet now. I sure wouldn't feel like being there at the house at this time. And maybe you can pick a nearby city where there is a museum, park, whatever or something that you could wander in, get lost in and enjoy. Take a book, so you can go out for a nice meal, read and linger over the meal. The teens can handle themself for a few days. Part of growing up for teens is learning to take care of themselves.
I like getting away like that and being anonymous when I am troubled and needing some relief.
