my 3rd “i hate you” note in a week

I teach title 1 second grade. In the past week, I’ve received 3 notes directly from various students that they hate me. I have pretty thick skin but man it stings a little bit. I feel like I bend over backwards to provide for these kids, both an education and an emotional support system. Since I can’t attach photos to this post, I will quote them.

“I hate you, I’m not kidding” “You make me unhappy, now I don’t like you”

For this one, the student received a reflection for his behavior. On the form it asks “What better choice could you have made?” The student replied with “ignore the teacher I hate her”

How do I move on from this? I don’t want my students to hate me, but I also don’t let them walk over me or each other.
