What can one possibly do in this situation?

I work at a school for kids with behavioral problems. The past month or two, the kids have been becoming progressively more and more out of control. In the past, we always all met and came up with a plan of how to handle certain situations…the plan didn’t always work perfectly, but there was a plan.

Lately, there has been no plan. Administration seems to have given up. The students come into class and act disruptively, are sent out, and are sent right back because the resource room can not control them.

This situation has become unacceptable to me, but I don’t know what to do. I realized a while back that this job has become the major source of stress in my life, and is even starting to affect my health. I am the only source of income in my household (I live alone). The economy is terrible, but I feel like I might walk out on my job soon if things do not improve. Help!
