So done....

I had posted on here before about a best friend that I had lost and whether to let it go or not because she decided to end our friendship over a message instead of being an adult and talking face to face. She is now messaging my family about things I either said to her when I asked her to delete people (my family) who didn't know off her Facebook and trying to get them to lie to me about how they know her. On top of it all, she keeps posting on social media about me. I confronted her and told her if she had an issue with me to just please take it up with me and not get everyone else involved. She then flipped it around on me telling me I was toxic, crazy, and all this other stuff. I'm at a loss at what to do about this.
