If you're stuck there for now, just Google some coping strategies and try your best to build an emotional wall so she can't touch you.
I dealt with a total nightmare like this at a previous job, though my tormentor was actually my boss.
Just a straight-up evil person—super insecure, bitter about anyone who seemed even remotely happy (which was everyone, and honestly, seeing people thrive is what drives types like her absolutely insane), and mentally unstable... and I don't mean that as an exaggeration, she was genuinely unwell. She literally fed on making everyone around her miserable.
My big mistake? Letting her get under my skin. I couldn't hide how much she annoyed me, and she totally lived for that power trip—knowing that her position gave her total control over me and everyone else... she loved that fear. Honestly, people are still scared of her, I just don't have to deal with it anymore!
It wasn't until I was actually quitting that the floodgates opened—I heard bits and pieces, and once word got out I was leaving, everyone finally felt safe enough to spill the tea. Turns out, I wasn't the only victim; she had been causing issues with tons of people long before I arrived, and whenever she lost control, she'd trash-talk them behind their backs. Some of the stuff I heard people were saying about me was just... ridiculous, truly pathetic.
I even had someone tell me directly that they knew she was abusive, but they weren't going to do anything about it (for a bunch of different reasons, obviously).
The people who seem "successful" or fine working with her? They've basically just mastered the art of not letting her reach them. She's way less aggressive when people don't push back—so they just play along to feel like they've won, which keeps her satisfied, while they just shrug it off and don't take her nonsense to heart.
I've been in the exact same boat; same type of person, same experience.
She even went behind my back to trash my reputation with some of my friends, telling them all sorts of nonsense...
But now that I've realized it's entirely her own issue—that all that malice comes strictly from her and nobody else—I try to give her as little ammunition as possible. I just keep my distance and avoid her whenever I can.
