Oh, and what someone said is crucial: document EVERYTHING. Have a notebook you keep under your mattress or something and write down the date, time, and description of what she says and/or does. Even if you don’t feel like it or it’s happened so many times that it doesn’t seem to matter if you write it down again. It establishes a pattern and even if you never need to show anyone else, it will help you to realize this is NOT your fault.
You can create a code if you’re afraid she might find it, for example 03202229 YF if she just yelled at you using foul language.
Taking pictures/recording is a GREAT idea. If I had had a recording device of some sort (this was decades ago, remember!), I would have had proof to at least show adults who wouldn’t believe me otherwise.
So here’s your homework: Start a notebook, and make a phone call. I’m rooting for you, BY Girl bas Torah. 🙂
