Need advice on leaving a job immediately

I am currently 21 weeks pregnant. And am seeking some advice.

Some background:

I am a nanny to two children who have serious behavioral issues. I have been working since September and have stuck it out, my last day being March 1. However, I just feel like I can’t do it anymore, even though it’s only two more weeks. The kids are VERY violent, don’t listen, and have no respect. They spend hours just beating each other up. Now I am no stranger to children and their behavior- I was a teacher and have also nannied for years- but this is something I’ve never dealt with. I have been kicked multiple times and leave in tears almost daily. I have pulled out all my teacher tricks and discipline strategies, but nothing works because there is no follow through from the parents. She works from home and while they are completely out of control, will laugh and shut her door calling them “crazy’s” or “psychos”. It’s laughable at this point and I feel I am being made a fool of.

Besides the behavior, these are some of the other things I have endured.

- I constantly get questioned and badgered about my covid safety. I am the one that is pregnant and so so cautious. But they go out and do the exact same things I am questioned about. Double standard much?

-I have called out twice, once because I hurt my back trying to wrestle the kids and another because we got almost 2 feet of snow. I was spoken to as if I am trash and beneath her, which made me feel like complete garbage.

- mentioned about, ZERO intervention about the behavior. All I’ve gotten in response is “they’re so sweet” “I love them” “he has a temper but he is so cute”.

Enough is enough!!!! I want to resign on Friday but I am unsure how to do it. Obviously I am very uncomfortable doing this and am asking advice on how to address this. I have the kids car seats and her credit card I will need to drop off. I am just trying to avoid the bashing of my character and crap talking of me to others (not that I REALLY care, but it’s never a nice feeling). I am also worried about a bad review on my care.com profile. I am working from home doing another job so it doesn’t matter THAT much but I still care about my reputation.

Any advice would be really welcomed on how to go about this. It’s such an uncomfortable spot to be in. Thanks in advance!
