OK Aristotle. You take your mom back to her home and you go back to yours. There is nothing wrong with that!
I'd say, if your mom is tormenting you, you go ahead and block her on your phone. Is there a risk she'll come looking for you at your place? Then change your locks, if she has a key. If she bangs on your door, you call the cops. If she threatens you with violence, call the cops. If necessary, you get a restraining order, and if she violates it in any way, you call 911.
But I suspect that maybe your mom isn't the physical assaulting type, but rather the type of person who thinks she's helpless, and she whines and puts up a fuss at all hours to get you to be her slave. I think the way to deal with that is to cut off communications with her. She can get help elsewhere--social services, senior services, a hospital, neighbors, other family members. She has money, so let her take care of herself for once. If she has a physical disability, she can arrange for appropriate care, or possibly move to assisted living. Sure, she might feel emotionally dependent on you, needing to whine and lash out at you whenever she feels like it. Well that's going to stop because you're not hearing it anymore.
You are responsible for YOU. She's responsible for her. You worry about YOU. She can worry about herself.
I think that once you get some time and space away from your mom, you'll start to feel a little better. It might take some time and adjustment, but right now, it sounds like you're having a trauma-based response, of fight or flight. Maybe your brain is working overtime, worrying about the potential repercussions, because let's face it, your mom is extremely disodered. But that's not your concern right now. You need to get back on track to taking care of YOU. That includes getting regular sleep, eating right, taking care of your finances and doing your job. If you need therapy, get it. Once things settle down, you can breathe a little easier and maybe have time for exercise, hobbies, friends. You deserve that.
Also, I don't want you to feel guilty. That's just your mom playing Jedi mind tricks on you. A healthy mom would be over the moon that her kid got a law degree and a job in NYC. A healthy mom would want her adult child to flourish. So you go do that, OK?
