Pennsylvania is a Judicial Foreclosure State, which means someone would need to be served papers by (usually) the local sheriff, and be notified of the sale date. You could call the sheriff to see if a date has been set on this home.
You probably have some time yet to sort this out. And filing bankruptcy can shut everything down for a while.
My best advice is to consult with a Bankruptcy Attorney immediately. Most offer one hour of free consultation.
The Chapter 13 stuff is filed in NC.
