Oklahoma Bankruptcy Lawyer Dan Nunley has a good blog post about over aggressive debt collectors and the harm they can bring:
If you are feeling the pressure of debt collectors, and think you need to discuss the option of bankruptcy, feel free to give us a call.  There is nothing worth losing your health over.  If you feel you are being pressured unduly by debt collectors, it is usually better to discuss your situation with someone before making any decisions.  As a law office helping folks file bankruptcy, we can discuss that option with you.
