If you accidentally remove your admin and bureaucrat rights and there's no other bureaucrats on your wiki to restore them, you should write an email to Wikia's Community Team using the Special:Contact form, giving them a link to your wiki and explaining that you accidentally removed your rights -- then they will be able to restore them for you.

Of course, please try to not remove your own rights in the first place. If you are an admin and bureaucrat on a wiki, there is never a need to change your rights, as admins automatically have all the powers that other user groups like rollback and chat moderator have.
