Most people don't pay much attention to their credit score, which is easy to do when you've always been able to pay your bills on time and haven't acquired much debt. But even the most responsible consumers can be hit with unforeseen circumstances such as a job loss or medical bills. Credit cards may be able to float the expenses for a while, but eventually the debt can mount up to a point where payments are no longer manageable. Missed or late payments can lower your credit score, but you may avoid bankruptcy, hoping to stop any further damage. However, sometimes bankruptcy is the correct choice, and there are things you can do to rebuild your credit score after filing.
