Thing I broke my site!Help please

Wow how very stupid of me, and how amazing how two small changes mess up my site (argh)

I changed wordpress adress to https://www.pixelsmithstudios.wordpress.com, it should be https://www.pixelsmithstudios.com ( I know that now)

and changed email adress to [ redacted, don’t post email addresses here ]

When I try to log in to https://www.pixelsmithstudios.com/wp-admin I cant log in be cause it redirects to https://www.pixelsmithstudios.wordpress.com which doesnt exist becuase I bought https://www.pixelsmithstudios.com form them as a registered domain name.

Any ideas? The site looks horrible and I need to fix this.
