Around 1:20 there's a scene with a shirtless character who very suddenly and roughly picks up his miniature greyhound, and the dog cries out, either startled or slightly hurt. He then puts the dog outside the room and closes the door. We see later that the dog is safely given to a relative so he's ultimately fine.
Technically no? The main character is sexually humiliated by her husband at one point, but there is no graphic onscreen r-pe to speak of, even while all of the sexual acts in the movie are disturbing to watch.
Hard to define this one - the main character asks for the physical abuse performed upon her but goes between relief and crying as it's happening. Hard to watch what she goes through either way.
The main character uses razors to cut herself (arms/leg/wrists etc.)
There's also a scene around 50 minutes in where a character is scraping the skin of another character with a shard of broken glass; it's implied he cuts her with it out of the frame.
Around 1:05 in a character cuts themselves in a hardware store with screws, nails, tools etc and is bleeding from the wrist.
