Nightbitch: A Novel

Does the most realistic depiction of early motherhood I've ever read include the feeling of turning into a feral animal? How could it not?

"She wanted to tell the girl: It’s complicated. I would like to be content, but instead I am stuck inside a prison of my own creation, where I torment myself endlessly, until I am left binge-eating Fig Newtons at midnight to keep from crying.I am angry all the time. I would one day like to direct my own artwork toward a critique of these modern-day systems that articulates all this, but my brain no longer functions as it did before the baby, and I am really dumb now. I am afraid I will never be smart or happy or thin again. I am afraid I might be turning into a dog.
Instead, she said, smiling, I love it. I love being a mom.”"
