Cant sign into youtube...

So yesterday i was on youtube all fine and everything,
but this morning i went to go on youtube and first thing that i thought was weird was that it didnt automatically log me on, then secondly it wouldnt let me sign in.
Its a password that is super easy and i have been using it for along time and i would never forget,
problem is i have no bloody idea what email i used to create my youtube so i cant reset the password unless i can find out what email i used somehow...
anyone got any ideas (apart from email youtube...)
