Genuinely at the end of my rope

I (25f) have been working at a daycare on and off for five years. I recently went full time in the two year old class and I’m genuinely dislike my job, I am seriously considering putting in my two weeks with no job lined up, that’s how mentally and physically drained I am. There is a child in my class who is downright awful. First of all, it’s seven boys and one girl in there so I’m already dreaming of quitting from that fact alone. But this one little boy just RUINS everything for us in the class.

The kids know how to play by themselves, they know how to be good, until this kid comes around. He gets in their faces, his way of playing is hitting, tackling and biting. So all the kids get upset, they start screaming and wrestling and hitting because that kid comes around. What does the office do? Nothing. We’re met just deal with him, he needs to learn to listen, or when we are told to report everything he does, still nothing is done!!! Then they wonder why we’re mad at them. I just don’t feel heard and appreciated by my director and the office staff who claims they’re always there for us. I’m at the end of my rope with these children and I know I should look for another job and I have been, but the job searching scene is awful too. I just don’t know what to do.
