Am I wrong for worrying?

So my step mother is dead obsessed with my hubby. They’re the same age (30) and they were friends before he and I got together. Well I just found out she’s in town and I’m freaking out. This woman is a woman that will purposely start fights just because she can. Has hacked every single one of my social media accounts because she was upset with me and posted my convos on my time line, changed my passwords so I couldn’t get on them anymore, when I was a teen she would take my phone away and send my texts to herself so she could post them on her MySpace.

She’s even stopped to the level of faking social services on me and saying I was abusing my daughter because she wanted my daughter! Social services threw the call away because it was complete and utter bull****.

And every time my hubby and I have had problems it’s been because of her starting stuff.

I’m worried that she’s back in town just to start stuff because she tried contacting him about a month ago and he didn’t respond and now all of a sudden she’s here and we keep having a mysterious van showing up at the end of our road. 🤷🏼‍♀️

I think he thinks it’s just my hormones talking but this woman is legit insane.
