I have bad news! If your account is not online for everyone to see, it's been deleted, that why your email address does not correspond to a disabled account.
You have been trying to access your account for 3 or 4 months but did not submit the document, hence we can only conclude that Facebook judged your account to be obsolete and deleted it from the server. Deleted accounts cannot be recovered.
I suggest you create a new account.
Good luck and farewell.
