Cousin is threatening me

My cousin is threatening to beat my ass because she some how found out I'm the one that called cps on her. Her kids are 13 and 15 and barely 3 pounds over weight. She was trying to get them to lose weight so she tried the tapeworm diet and gave them pills that had tapeworm eggs in them. Cps took her kids a couple days ago and father got temporary emergency custody. She has been doing everything she can to not let him see his kids because she's bitter so I know it pisses her off that he has them. Both her kids had to go to the Hospital and I've been talking to my cousins ex for updates. Their daughter has passed the tapeworms, son has not yet and he's running a pretty bad fever but he should be okay. She has been blowing up my phone, posting on Facebook about how I'm a bitter bitch with no man and no kids so I got hers taken away and now I have her friends threatening to fight me too. My neighbor said she noticed some girls driving around the apartments asking for me while I was at work. I'm trying to lay low until this whole thing passes but it's getting out of hand. I never wanted to hurt her, I just wanted to make sure those kids were okay.

Edit: Okay I just realized I may have been the only one she told that she was giving them tapeworm pills so when cps got involved she pin pointed it to me. I just realized that.
