Oh dear. Is there any way to edit it at this point?
The only time you can get an edit from an admin (post-posting) is if you accidentally
included personal details like address, phone number, etc.... They'll edit out those details [adding the clause that the post was edited by admins] but won't delete posts or threads.
The only time they delete posts or threads? If the post violates the spam and/or Terms of Service policies (especially if it's a trolling post that incites violence, etc...).
I really doubt any of these reasons are relevant to your original thread above.
