I just can't anymore...

I want to quit. At the moment, it just isn't possible. We are a two-paycheck household. I am trying to wait until the end of the school year. We call for help. No response. Kid trashes a room. Allowed back the next day with no consequence but a parent phone call. Teachers and other staff are physically beaten up all day long. Only when a student hits a supervisor or other admin is there a consequence of suspension. "You got this!" is the support given when we need help. I am physically and mentally drained.
