I'm having anxiety over this?

Back in March my sister accused my mom of hitting her and pouring water on her. And my mom poured water on her. She was drinking, yes but she never hit her.

Anyways, my sister has a protective order on my mom and has since came back in the house (mom's house). They can't be around each other and my sister is making messes, has the garage filled up with her shit.

My brother is on speaking terms with her and nobody said she could stay here.

But it's been a few weeks I told my mom to call the police.

It's so stressful, my sister is acting super shitty. She's 45.

I don't talk to her nor will i ever. But she isn't leaving.

Last resort is to call the police. I told my mom to call them cause I feel like they would be less likely to arrest her cause she is following the no contact order.

I'm having bad anxiety over this, cause apparently she talked shit about all of us to my brother like last week. WHILE SHE WAS Staying there.

But November 6th my mom is calling the police if she isn't out. And I'm very worried my sister is gonna plaster us all on fb again and come after my job and get me fired. My mom plans to leave and call the police and I'm gonna show them where the room she is in.

My mom wants me to warn her. But I don't want to talk to her. I mean my brother already said that my mom was gonna call them. But my mom wants me to tell her that by November 6th the cops will be called but I dont wanna talk to her.
