A child is kept extremely isolated from the rest of the world, and it is implied that her mother wanted them to kill themselves together. A separate mother is also very curt/unkind to her daughter, cursing and restraining her at one point.
There are multiple instances where a character has an anxiety attack/flashes back to a traumatic incident. They struggle to breathe, briefly hallucinate, and cry.
A woman drowns herself in a river; it is referenced through dialogue as well as shown in brief clips. Another character later tries to drown themselves, unsuccessfully.
