How can this be worse than sleeping on top of her parents' graves, saying Kaddish so many times the words ran together like nonsense, worse than sitting for days by the Pripiat River, watching for a little sock or Sophie's blue petticoat, sitting in the mud in only a nightgown and blanket, until the weather changed and Mariam came with the flier for America?
Inside, keep your body off the ice or ground (the Inuit put their sleeping blankets on top of a bed of sticks and reeds) and create heat-trapping "loft" (it's what keeps you warm in a sleeping bag) by layering a few small blankets or big trash bags, with leaves or crumpled newspapers in between.
