Leaving after one month

Got hired into a program at a charter school where they trained me for a few months. Spent a couple months in a classroom with a great teacher and got adjusted. I was offered a job to teach 6th grade social studies in May. July rolls around and I find out that spot isn't available anymore. Could have stayed and been a TA but the principal thought I was ready to have my own classroom (I think I was tbh). I got moved to a brand new school under the same company. The school was opening in the lowest performing district in the state. Got there, it was basically being put together on the fly. I was then told I would be teaching 7th and 8th grade, okay fine I think thats doable. Then I'm told I'll be teaching 6th, 7th and 8th grade. Mind you I don't get a TA which I was used to since I was always in a classroom with someone else.

First month has been a disaster, kids bombed their first test. Principal is trying to support me but I am so demotivated. I literally don't want to do a thing. Behavior is out of control, we just now got someone who can take kids out of class. All the teachers at the school are worn out too tbh and most of them have not taught before. I'm pretty sure if I leave, a lot of people will follow. I feel bad for the kids, but I'm not helping them, they might as well sit in class and do nothing at this point tbh.

My mother worked as HR for the school and was part of the reason I heard about the program. Turns out my mom left a month ago cause she did not like the way they do things over there. Talked to her last night and she's fully in support of me quitting. I just moved into an apartment so that scares me tbh but I can't just keep doing this, I have a lot of customer service and call center experience so I'm hoping I can find something.
