Anyone know how to get into my Flickr account?

I have had my Flickr account for a while. Recently Flickr and Yahoo fell in love and got married. Now you have to sign in with your Yahoo email account in order to access your Flickr account. I don't have a Yahoo account. Well that isn't completely true. I do have one, but it isn't hooked up to my Flickr account.

I am sure I could figure it out if I wasn't sleep deprived, but that isn't going to happen any time soon. Anyone want to hack my Flickr account for me! ;D
