Have you ever write in a journal about someone and that someone find out?

Yes, I was instructed by my doctor to write one about my ex mother in law to log how she treats me and to prove that Things weren't all in my head. My ex and his sister found it and read it. They treated me appallingly but never asked me about it and I didn't know for quite some time after. I gave it to my ex when we spilt, ten years worth of abuse that he just sat back and allowed happen.
