How to get my sister to stop harassing me after fathers death

How do I get my sister to stop harassing me and my children? I don't want my sister to have contact with me or my kids after this behavior?

Me and my sister do not have the same father. She has never met her father and when she has reached out to his family, they are not welcoming to her. They have told her to stop contacting them the times that she has tried. I know this is really difficult for her and causes her trauma.

My dad passed away about a year and a half ago. This has been really difficult for me and I have made great progress in healing from being sad about this. After my parents divorced, I lived with both parents. There was a period of time that my dad moved further away and invited me to move with him. My sister was very jealous as she was not invited and their relationship changed after that since she is not his daughter.

I am a lot like my father in many ways and we had a special relationship. Since we are so much alike in many ways, we understood each other’s sense of humor and even if we would argue with each other, we never stayed mad at each other and got along great. I remember as a child we had a close relationship also that him and my sister never had even when she was living with us while my parents were married.

He used to take me to the movies and she was not allowed to go. When I would get back home, she would hold me down and paint me with finger nail polish. Her and her friends once held me down, hit me in the head with hard blocks, and painted my whole body with fingernail polish. She was not allowed to have sleepovers after that and would pitch a fit when I had sleepovers. She dealt with a lot in childhood and was hospitalized , had panic attacks, and was very disruptive in the household.

After my father’s death, she started lying about me to my family. She started lying about me to my brother, who is not her brother as that is my father’s child and he is not her father. She started faking panic attacks when I see her. She came into my home and went through my things while I was not home. She stole a vape from my grandmother and when I asked her to return it, she twisted my arm. This was hurtful to me as she used to attack me when we were growing up to the point I moved in with my father to get away from her.   I know her not having a father and her father’s family rejecting her is hard on her.
