Big Problem: Domain Mapping Removed Super Admin

I made a really stupid mistake and entered my main domain inside domain mapping and even set it to primary. How my other 3 sites work but my main site,, has reverted to an initial state as well as removing my super admin and also when I press on Network Admin it goes to: http://wp-admin/network/ which doesn't exist of course. I have no acces to the plugins from the dashboard to fix domain mapping. Any suggestions how I can disable domain mapping or remove my own domain from its list? Thanks
