Thank you, Everyone! I really appreciate this.

Reading your replies made me thinking... So basically, I have to prove that I have been in this country ever since my entry when I was 13? Until yesterday, I thought I just needed to show I came here before the age 16, show I have unlawful presence as of 11/20/2014, and then prove continuous residency for the past 5 years, not the past 20 years...
