i can’t log into site admin.. it shoots me to oops, ftp tutorial

when i try to login to site admin… it shoots me to a page not found… i know this is because i tried to rename my domain backslash from wordpress to freelancer (ex. https://www.mydomain.net/worpress to https://www.mydomain.net/freelancer) through the dashboard under OPTIONS heading and updated file and idiotically locked myself out so to speak. since then i have opened my wordpress ftp client files and successfully uploaded all of its contents onto my hosting site so Now my domain name opens my wordpress site without any backslash at all! woo hoo but how do i restart or refresh my site admin login and get rid of renamed domains, not needed now.
PLEASE i am at your mercy
