Bad. Very bad. Keep at least one copy of your secret key on a save medium,
eg. an usb-stick or a disk in your bank deposit box.
Facing your problem, i would 1st try, to recover the key from your
harddisk. By 'wipe' you mean a simple delete? If so, you _may have a
change without paying a lot of money for a forensic professional.
You may take a look at sleuthkit[1] or 'The Coroners Toolkit' to look at
your HD for deleted files.
If the name information for your secret_key is gone, you can possibly
identify it on its size.
Of course, you have to stop writing to this harddisk immediately! Take an
image with 'dd' to another harddisk and work with this image further on.
Good luck!
Andreas
