Microsoft account problems.

I was trying to login into my xbox live account ForsakenXV and I got my password wrong a few times then when I finally got it right its telling me I have to verify that its my account. The problem is, when I made that account years ago I accidentally messed up the back up email address so I can't get it sent to me. I've long lost the gmail account password since its been years since I actually used it. Its been so long I can't remember the things I've had in the email account either,  other then my name and birth date I have no idea about any of the other information. I need someone to help me with this, for I've long countless of hours worth of gameplay on my xbox live account.



Thanks.
