No access to wp-admin

I built a new wordpress site and, while I was working on it, I saved it into a sub-directory (www.tyranena.com/wordpress2) so the old one would still be active.

I’m now ready to make it viewable as our official website. I thought I could simply make it “live” by redirecting the wordpress settings page to our domain name. Yeah, that didn’t work. AND now I have no access to https://www.tyranena.com/wordpress2/wp-admin to be able to fix it!!

HELP. PLEASE. I could cry…
