No one understands

So I’m 10 weeks 1 day. I work as a preschool teacher. My class is mixed of 2s and 3s. Well lately this kid has been hitting me for no reason, scratching me, and spitting at me. It came to the point where I had a break down today cause this job is stressful. I told my boyfriend I was going to put in my 2 weeks and find another job. He just texted back whatever! Like I’m really stressing out and he doesn’t care.
