Page deletion is primarily assigned to users with particular rights, such as admins and moderators, Wikia unfortunately doesn't allocate a user to delete their own pages, they instead gives the users with the user rights to monitor all the pages and delete those that are marked for deletion or are requested for deletion.

So, to answer the question, you'll need to ask someone with user rights, (Admins/Mods) etc. to delete your page for you.
