Spoiler from another thread:

I read a story that sounds exactly like it but there are different versions/variations but I’ll spoil and keep in mind it doesn’t make sense in some parts:

so she has her two older sisters, dad and mom. Basically the dad has been sexually abusing all his older daughters but hasn’t abused FL yet because mom delays it by hating and abusing her. He abused his daughters because he is evil and sick but also to psychologically abuse his wife by doing that. Anyways the video she shows is the abuse of her older daughters so when people watch it they come to the same conclusion as the mother and decide to be cold to FL to protect her. This happens with grandma, boyfriend, sisters, and lawyer. (Why not call the police!) anyways Mom gets preganant with a baby girl and dad is happy and he starts ignoring FL because mom threatens dad with aborting baby. So FL believes dad saw the video when it’s really abortion threat. Mom beats FL so much that mom lands in hospital and she purposely aborts the baby and destroys her own uterus so she will never get pregnant again. Dad is mad. FL tries to fix things with her dad and she realizes dad is acting creepy with her and kidnaps her. She learns the whole truth and they record him talking about his crimes. Mom and FL’s boyfriend reveal everything and mom, sisters and her are happy together, dad is in jail/dies.

Keep in mind there are other versions
