I have accidentally deleted my alternate iCloud (email) address. Are there any possibilities to retrieve it back because my iPad is connected to that email address, and now, I can't log out from it on my iPad, because it doesn't exist?

I have alternate icloud email attached to my iPad and I accidentally delete it from appleid.apple.com. And now I can't log out that iCloud account because it doesn't exist and it can't recognize my password.
