It sounds like you have done what you can to protect yourself (credit freeze, law enforcement etc.) I am not sure what your bank will do but I can’t imagine they will pursue you for a crime committed against you. Have you changed the bank account you deposit your Social Security check into? If not, talk with your bank. It would seem to be a reasonable precaution.
A debt management plan sets up a payment schedule for you to repay your debts, with the goal of helping creditors receive the money owed to them and ultimately improving your financial and credit standing. By voluntary agreement, you deposit funds with your credit counseling agency each month, who sends those funds directly to your creditors. It usually takes 3-5 years to complete payments under a debt management program, after which you may be able to reestablish credit.
