Error with hotmail login


New Email
A while back I had done something where it combined or merged an @live with a @gmail account I had (not sure if that's what it really did but the best way I know how to word it.) This was a few months ago and ever since then I've tried to access my @live on like I always have, but no matter what password I use its always incorrect. So logically, I tried the password reset. But I had never sent emails or created any folders on there, and had forgotten some information that it was asking. So whenever I requested for a password reset I was always denied because of it.
So now I'm stuck. I have no idea how to access this email and just about everything I use is connected to it. My steam, Xbox, you name it. So I need to know how I can get this account back.
