My first D.C. public school visit

Today was my first day visiting 8th graders at a DC middle school. There was about 10 kids, 7 girls, 3 or 4 boys. We asked the kids to answer some questions on poverty. This was the first time that I've ever been in the DC public school setting, and let me tell you that I was anxious the whole time. Kids were slapping, hitting pushing, cursing, yelling, running, getting out of their seats, drumming on the desks, doodling, throwing balls at each other, locking each other out of the classroom, taking other people's things, ignoring adults, giving attitude, not listening to directions, and bullying others.
It was the most chaotic, stressful 1.5 hours I've had in a long time. I've never attended school with that kind of environment. I don't know if I could handle that everyday like those kids do.
At one point, I guess I had an upset look on my face, because a boy sitting next to me said, "You don't like the students." Then he got slapped in the back of the head by another boy for conversing with me and not doing the paperwork.
It's going to be so hard to get through to these kids. I actually do communication work, but I'm going to go to school at least once a week to make relationships with these kids. Maybe they'll eventually begin to trust and listen to me.
