It indeed sound like you did an export of the public key only. In that case
you're sort of f*cked.
However, there are at least theoretical chances of recovering your secret key,
but somewhat slim. You could use a forensic tool such as EnCase to try to find
the key (via the secret keyring) even after formatting the drive, should those
sectors not be overwritten.
Since you most likely don't have that particular tool at hand you could probably
find some other data recovery type of tool for that purpose. Use google. Some
more capable tools may be offered with trial period perhaps.
EnCase could possibly be found at nasty pirate bay type of sites too, but
obviously I wouldn't dream of suggesting such a thing to you.
But I'm quite sure there are some capable tools available the right way too, do
a search. Possibly even some of the data recovery tools from Sandisk etc could
be used if you're lucky.
The first thing to do though is to immediately stop using that disk, so that
you're not writing over those sectors with new data. Chances are you already
have done that, but if you're lucky..
