I have had a critical error on my website, and I'm really fucked

WP doesnt send me reactivation links - admin email, new admin email, reactivation email, all user emails are changed to mine - still recieve nothing.

I changed the theme that was causing the issue (reverted to the broken theme again) but nothing happened, except that i was now able to access the login page.

However, no matter if I type in the correct password, it just doesnt work. I have PHPMyAdmin opened up, I can see all users and their Passwords, yet WP says those are wrong.

Help.
