I came across a JW video on Youtube. It was produced in 2015 by the Watchtower.
It's titled Child Abuse - Jehovah's Witness Perspective
A sister tells about years of child abuse by a family friend when she was younger, this appears to be before her family became JWs. She explains how finding Jehovah has helped her in many ways. She says that she still struggles from time to time with negative feelings and emotions but she finds physical excercise helps, as well as praying down on the beach.
The bottom line is that if you've been abused try to get rid of those negative feelings and don't do anything practical about it like informing authorities or seeking professional help.
