Can't get into my hotmail account at all!

Hello,

I made a hotmail account a few years ago now with my dad as my first email account, I must have been in year 5/6 (10/11 years old) which isn't very old, I am now 17 and have a new gmail account which I made recently because during the winter my hotmail blocked me out, it explains that I need a code to log in, I get this code from a yahoo email that is 'apparently' mine, but I have never ever made a yahoo account for myself. That's problem number 1, I can't get in to the yahoo account to get into my hotmail account because I didn't know my yahoo account existed...

Secondly I have learnt that there is a way to recover it, by filling out a form (after the security questions (which I have also forgotten, IT WAS ALMOST 7 YEARS AGO HOW AM I SUPPOSED TO REMEMBER?!)) that include things like my age, post code etc but as a 11 year old I don't think I knew what a post code was or if I felt safe enough to put my home address in or my real name etc. so now I am stranded with nowhere to sign in or get into my email.

This is ridiculous, I literally only want to get into my account so I can activate a code to change the email address I would be using for a video game! - which I haven't been able to play for the past 6 months because I can't get onto my b@stard hotmail account.

Does anyone know anything I could do to fix something like this? Phone them up? I don't think they would believe me if I told them this story. Thanks anyway!
