As unlikely as it may seem, there are ways around those old bills, that seem to keep popping up, and bothering you constantly.
First, consider paying, only the bills that are the most important, such as your house note, utility bills, car note, insurance.
If a bill comes in that is a credit card bill, hospital bill, etc., send only what you can. Do not send the minimum amount, since this will run you short on your money. Send them what you can afford to send. Even if it is just a dollar a month, if they accept it, then you are in good standing. If they refuse it, be sure to keep the letter of refusal, along with the payment showing where you attempted to make the payment. Keep those documents together. When it comes down to it, and you show proof of trying to make a payment, and honor your obligations, then the courst, credit bereau, and anyone else, will have to stand with you, since you will have documented proof.
