Hi, welcome to the forums. You have come to the right place. Please tell us how much each loan was for and from which lender. Also, how much you have paid each one so far and the State that you live in. That way we can help you determine what you legally owe.
You may have to close your checking account immediately so that you can breathe and deal with these companies on your terms, not theirs. Before you do that however go to your bank and see if they will work with you by placing your account on deposit only status. If you do have to close your account be sure your bank does not have a policy to force open your account for electronic payments. Tell your payroll dept that you need to get a live paycheck for a while.
