Have you tried enabling "Show Hidden files" (or whatever similar option you have) to see it is not converted (or moved) to some hidden folder? Least possible thing, I know, but just to make sure.

Based on the results and some personal understanding, I think your only hope is some data recovery software, and testdisk is on top of my list of recommendations.
Doing another fsck on the partition may help, but it may also make the recovery more difficult by making changes to the file-system. So I would prefer to scan with testdisk first.
Try booting into live session, get connected to internet and install testdisk with -
Then run it with-
sudo apt-get update
sudo apt-get install testdisk
and follow the instructions here to see if it can find your lost home/data : www.cgsecurity.org/wiki/TestDisk_Step_By_Step
As a precaution, the first thing I would do is to stop using the partition. For using recovery tools like above, I would use a live media and would only use the partition in read-only mode.
