She abused me and then blamed me for the abuse

She is my sister and I stayed with her interstate. She started bullying us and calling us names, swearing at us, you name it!

When I left one morning she seemed to think that me leaving without telling her was worse than everything she did to us. She stalked us in person and then when we went home again stalked me through social media. She sent abusive emails. She said the most awful stuff about me and posted my personal details online.

When I got angry and wrote back to her she used these replies to paint me publicly as the unstable and abusive one all while denying every single bit of the abuse and stalking.

I stopped playing and cut her out. I havent spoken to or looked her up or anything! She's now dead to me. This is the ONLY way to escape a narcissist.
