As you forced it to reboot, you may have damaged the directory.
You could try Safe Mode by starting (or restart) your Mac, then immediately press and hold the Shift key. The Apple logo will appear on the display. During a Safe Boot the system will take longer to start up than usual as it is running a disk scan.
If you can get to single user mode (boot up holding down Command+S) and type the following command:
fsck -fy
Followed by the return key.
The first command allows the hard drive volume to be made accessible and writable in Single User mode, the second runs the Unix file system check disk, with the flag to force it to run on an HFS-Journaled drive and to fix errors as it finds them. Apple's MAN page on fsck
When it has finished running you will be back at the command prompt. I would recommend running it again to see a clean bill of health.
If you want to look for your user's folders, you can from within Single User mode. First you need to mount the filesystem so you can read it:
mount -uw /
followed by the return key.
Then go to the folder with the user home folders:
cd /Users
followed by the return key. Then list the contents:
ls -lsah
followed by the return key.
You should see the name of your user account here. If you would like to verify that your data is still there you can run the disk usage utility:
du -hcd 1
followed by the return key. Or another way that displays a little differently:
du -hs *
followed by the return key.
This command will show the total of the folders as well as the size of files.
The switches used are h for human readable sizes (not blocks), c for a total, and d for controlling the depth to only show the top level. You can change the number to tell it to calculate and list subfolders in the same list or use 'cd foldername' to move into the desired folder. Once inside the folder you can use 'ls' or 'du' as above.
To exit this mode and start up normally, type "reboot", then press Return.
