EXPLOITED TEACHER IN NEED

After working for 3 years with no vacation pay, no holiday pay, no pay for Christmas or Easter breaks, I have been sent home with $115 for my last month of work. I allowed this school to underpay me for 3 years. I worked 10 hour days, no lunch break and ran afternoon classes every single day. I am so torn. I'm on the eve of 50 and I'm burnt out. I'm caring for a disabled husband and my 2 grandchildren. This latest event has left me depressed beyond reasoning. How do you pay a grown woman $115.00 as their final monthy paycheck and justify it. I don't know if to cry or freak out. I only know I'm in trouble. I have bills and it seems impossible. I'm searching high and low for another job but how do I make it until then? My landlord has been gracious and lenient. He's been patiently waiting and by the looks of it, I still can't pay him. Please help me to so right by my family.
