You have a borked install, it seems. You should ALWAYS be installed into that 
file if you are the default user. i'd say use the command visudo, but since 
you're not in sudo file, you can't xD

You can boot in recovery mode, mount the partition and add the following line 
to /etc/sudoers
clay        ALL=(ALL) 

which will give you full root access using sudo, under that account.
