I need to access my old Y! email.?

I am currently blocked out of my first ever email. I guess I must have had a typo in my birthday or something because that's not working, and the account is from 9 years ago. I recently changed all of my pwords out of paranoia because my ex got a hold of one of them, and now I can't remember the pword. Is there a way I can prove who I am? I could go so far as to show yahoo admin my photo ID if need be. It's a very important account with a lot of saved emails that meant a lot to me. Even emails from people who have since ped away, and pictures of my nieces and nephews. Any suggestions would be appreciated. Thanks for your time!
