This is the kind of horror that stays under the skin, since it's so close to real life as to not be that different. I've had a relative who was a nurse that broke her back in her job, which happens often in nursing. I also know parents of special needs kids, and the difficulty of doing so. It is one of the hardest jobs to care take for others, and can one of the most depressing, but also one of the most rewarding. I somewhat feel for the nurse in this story, but I also know caretakers who don't let the regular hard work and pain get to them this far, without taking a breather or asking for help.
I prefer my horror to be fantastical, as real life offers more mundane but far more painful horrors beyond the shocking monsters or weird deaths and tortures that some horror stories offer. I like horror I know can't happen or most likely won't happen. But, I liked this story and it was pretty disturbing. There are so many silent horrors that go on without our knowing on a daily basis, behind closed doors and away from regular lives, and this one rang truer than others.
