Yes ByrdMan, I know EXACTLY how you feel, and good for you! You ARE doing the right thing.
For now, take a deep cleansing breath, maybe back off of thinking about it for a while, and note the others' responses.
So many people have benefited from your wisdom, and comments.
The attorney calling probably CAN help you resolve the issues, IF you pay him your money. very misleading, but in essence it is true. is the amount astronomical, or just a little amount owed?
If it's not reporting, is it worth the peace of mind of keeping it off your CR's just to pay him?
Sorry I'm not much help, but have limited experience in this field. I'm sure others will respond and offer their normal wonderful opinions/advice.
