How To Get Into My Hotmail Account?

Basically, I created a one-off Hotmail account for my Tumblr. Unfortunately, my Tumblr got a virus and I had to change the password for it. Though I completely forgot the password for my Hotmail account. I cannot remember whether I lied about my age, name, whatever? And every time I try to set up a new password….it tells me my information is wrong.
Can anyone help? I really want to get into my Tumblr – ha, yup i’m sad.
Any help would be appreciated. x
