if you didn't start an instance of screen to begin with, you're out  
of luck; screen can't help you reattach to any arbitrary process,  
only to other instances of screen.

does nano have a robust autosave/autorecover facility?  if it does,  
just kill the nano process and start another (perhaps this time from  
within screen).  if not, curse your bad luck and consider using vi  
next time, which can deal with this sort of problem.
