. . falling out of yourself
Being raised in an unstable household makes you understand that the world doesn't exist to accommodate you, which ... is something a lot of people struggle to understand well into their adulthood. It makes you realize how quickly a situation can shift, how danger really is everywhere.

And an unstable childhood makes you appreciate calmness and not crave excitement.
