Living on cash translates into living within your means.
This is true and it's a lesson I learned and eventually was able to thrive and my 1st wife failed to learn and probably has the jacked-up credit to show for it, even now.
Here's the thing about Bankruptcy. I typically don't advise it unless your creditors are taking you to court, or you are in debt over $100,000. A Civil Judgment on your credit will do as much damage as a Bankruptcy so you might as well do it and not have to have your wages garnished etc. Most creditors will not waste their time taking you to court unless they think they can collect thousands of dollars and you have the income to pay it. If you're unemployed, they won't waste the time trying to sue for money they will never get anyway.
They can piss and moan and harrass you and put you in collections, but unless they take you to court, that's all they can do. And they can only collect on the debt 7 years from the Original Delinquency that led to them charging it off, etc. Even if the debt gets sold to 10 different collectors, they still are legally bound by that. Extending the collection period is called "re-aging" the debt, and it's illegal. I've busted a couple of collection agencies doing this and they got hammered by the FTC.
Once a debt is Charged Off, it's considered as dicked up as credit can be. It will be dicked up even if you pay the charge-off or settle for less money. Let your conscience be your guide, but if you do settle, get it in writing or it never happened. If they sell it to a collector both accounts will be on your credit report 7 years from the ODD.
So basically, if you went down the tubes 2 years ago and they are collecting on you, they can only do it for 5 more years.
How bankruptcy screws you is that it is a derogatory public record and it sits on your credit 10 years, not from the ODD, but from the day it was filed in court! You just added 5 years of f'ed up credit to your life if you are in the above situation, because even though the individual debt falls off, the Court record stays.
