By "Debt Collector Disclosure Statement" you mean a request for validation under the FDCPA? That isn't going to make a lawsuit go away (assuming one has been filed). Also, if the lawsuit was filed in advance of the running of the statute of limitation, the lawsuit is timely. (In some states they must make a reasonable effort to serve you before or within a reasonable time after the expiration of the limitations period.)
Was the letter you received from a lawyer offering to (allow you to hire him to) represent you in the lawsuit? If so, I expect that you'll find that a lawsuit was filed and there's probably a process server charged with serving you with the summons and complaint.
If this is the whole of your debt, $9,500 isn't insurmountable for most people, even after a serious setback like you've suffered. But if it's the tip of the iceberg it may be time to consult a bankruptcy lawyer.
