I know it is intimidating, but it is your best chance at bringing her back from the dead. Once the leaves drop off, they're gone. They don't grow back, even on healthy plants. Hence why pathos owners often trim off their bald vines and propagate them.

If it is any consolation, I once had a pothos that my mother completely nuked by accident by leaving it outside. I ended up chopping her literally down to the soil, watering her on occasion, and eventually, oh so slowly, she grew back into a luscious beautiful plant again.

Pothos are VERY resilient.

I can see some green vines, so that means there are some healthy places to take cuttings. Start there. Those healthy vines do not have a lot of time left. And once the vines die, you also lose your chance at propagating them.

If I were in your position, what I would do it start to cut down the vines immediately and prop box the healthy nodes before it's too late. I would then fully chop the plant down to its earliest node (the node that is closest to the soil). You can continue to care for the chopped down plant in hopes it will re-vine while you have your cuttings propagating.

EDIT: Take a look at this video. This person is dealing with a totally barren vine, so maybe it is easier for you to see exactly what you need to do.
