First you need to calm down... Secondly here is the exact path for disabling a WordPress plugin from your Cpanel and server:
1. You can use Cpanel and the "File Manager" in it and go to "wp-content" >> "plugins" and simply rename the plugin you want to DE-activate. If you want to turn-off all the plugins you can rename the whole folder "plugins" to something else! It will show that all the plugins are deactivated due to an error. And - ready! :-) BTW I am using an FTP program called FileZilla for the same operation - in my opinion - it is easier and much faster :-)
2. The second way is to go to the PHP my admin in your Cpanel, find the database of your site (be careful about it!), find the table named: "wp_options"; Then go to active_plugins (it might be on the 2nd page of the table) >> press edit from the options given >> delete all the information in it! - it will deactivate ALL YOUR PLUGINS! You can also copy and save it just in case! :-)
