Deleting a Facebook account that you are the admin of is relatively simple. To delete an entire page, log in to your personal account and click on “Settings” at the top right-hand corner of your page. From there, go to “Manage Pages” located under “Your Pages” on the left-hand side menu. After selecting which page you wish to delete, choose ‘Delete Page’ from the bottom right corner of that page's settings tab. You'll then be prompted with several options for permanently deleting the selected page; once done, click 'Confirm'. However it is important to note that when leaving a Facebook group or deleting a profile as an admin, all posts made by other members as well as any documents will also be deleted - so please make sure everyone has saved their content if needed before going ahead with this action!
