HELP !!!

HELP!
IM NEW TO WORDPRESS, AND TBH FINDING OUT AS I GO ALONG.
I’M CREATING MY NEW WEBSITE USING A TEMPLATE.
I WANTED TO MAKE MY WORDPRESS THE HOME PAGE ON MY SITE (WWW.NICKSTERN.COM)
TO ACCESS WP BEFORE I WOULD VIEW http://WWW.NICKSTERN.COM/WORDPRESS
I WENT INTO WORDPRESS AND CHANGED THE URL FROM http://WWW.NICKSTERN.COM/WORDPRESS TO http://WWW.NICKSTERN.COM HOPING IT WOULD MAKE IT MY HOME PAGE. HOWEVER…
NOW I CAN ACCESS MY WP SITE… HAVE I LOST IT ALL?
