Help! I can't pay my payday loan

I have recently had to get a loan and, then another. I have never been in this position before and I have been paying my payday loans back for several months. But know I am facing not being able to pay them back at all. I have to move because of no money and facing this with fear. I have 4 loans from 4 different places. This was never intended and I feel awful. I need help to know what I should do in this hard time. The loans equal out to around 1,600. I am in Ohio. I also have a bank account and have given them personal checks. Because I will not be able to pay them should I close my bank account associated with them before they cash them, should I let them go into the bank and be faced with the bank charges and whatever they will do? PLEASE HELP
