If you can leave and find a place to live, it is better than living with a narcissist who doesn't respect your privacy.

My parents also would barge into my bedroom whenever they liked, after a big argument, my dad respected my wishes, but no matter how many arguments about privacy we had, my mother never listened. I began to just be naked whenever I was in my room alone, and she stopped. When I wasn't in my room, she would still enter, but I didn't keep a diary and my computer was encrypted.
