My teacher's salary has decreased by 14.12% in a year. Where am I going to pull money from to pay for my kids' lunches?

I'm in tears. I pay out of pocket to pay for my kids who cannot afford lunches. I want to keep supporting my kids, but I don't know what to cut and I'm scared. I've looked at my budget and I don't know where I'm going to come up with the money. I've already cut back almost all my groceries, I'm driving less and canceling things I wanted to do over the summer. At some point, I'm going to have to cut this out. And that's just heartbreaking. I feel I'm being asked to do my job and pay for it.
