Then you've lost all documents saved in the default location (which is documents). you may have other files, where you saved them to the desktop (my wife does this all the time :grr

or other directories not withing documents.
I fear you have major issues as yet undiscovered - - do this:
login as Admin and get a command prompt (start->search and enter CMD and hit enter)
now type
and allow the system to reboot
when it does ( it will take ~30-60 minutes depending upon the size of your hd),
login as your normal account and attempt to access documents again
