Writing a book

I’m someone who has written several books but never published them. I think I’m going publish this one though. I’m working on a book that’s different from my others. My other books are love stories and mysteries but this one… it’s about me and it’s about domestic/sexual abuse. I went through a bad relationship with my ex at 16-17 years old and it was hard on me. My parents and family still don’t know what happened and if I publish this, they’re going to be in for a shock if they read it. I’m writing it to help bring awareness to others and hopefully stop this from happening to other people. It’s also just so I can vent. Sometimes I feel trapped and alone but I want others to know they are not alone. I’m still struggling and it’s been three years. I just hope when I finish it I can find the nerve to publish it.
