Domain change

I accidentally changed the website url and now i can’t access the wordpress to change it back to the url that is hosted and viewable by godaddy.

The website is fhssc.com and is hosted by godaddy

I went to the settings on wordpress, general and i changed the Site and Domain url to fhssc2013.com and now its not viewable, probably because its not hosted.

Is there a way to fix this? I just want to log back into setting and revert back to the URL that is hosted
