NEVER NEVER NEVER do 'sed 'foob' myfile > myfile'. ALWAYS redirect sed
output to a temp file, then mv the temp file to the original file.
As someone else mentioned, your file is probably gone. It *may* be
possible to recover the data, or it may not. Here is a link that might be
useful in giving examples of recovering lost data on UNIX systems:
http://www.samag.com/documents/s=1441/sam0111b/0111b.htm
Your ability to recover the data will depend on a combination of luck and
amount of disk activity since the overwrite. I don't know enough about
the internals of FreeBSD to know if there are any tools for lost file
recovery.
