As I understand it, the OP is more focused on recovering his email. This is right? Or are you worried about private messages in your PM on the forum?
I am not worried about personal message of this forum . i am worried about my some personal document like photo, nid , pasport etc. which document i have stored on google drive and dropbox.
To restore email, if a hacker hacked it, then you probably registered with a phone number, so try to restore using your phone, or backup mail if you added it to your account.
i am still trying it . but maybe hacker changed all my recovary. the hacker is much smart.
