If you are userid 1, I don't see how you can change it. You can also check this setting in the config.php file and see if your userid is there:

	//	****** UNDELETABLE / UNALTERABLE USERS ******
	//	The users specified here will not be deletable or alterable from the control panel by any users.
	//	To specify more than one user, separate userids with commas.
$config['SpecialUsers']['undeletableusers'] = '';
