Why do I feel slightly embarred that I was obsessed with Justin Bieber?

I do. I do know all his videos (mostly) even his unreleased songs like Won't Stop, Latin Girl and Ride. yeah memorized them and kept on listenin to them. & his videos are on my ipod. & bought all his albums even the never say never remixes and even printed his collage of pictures. But when i am in school and people call me a Bieber Addict! I feel so embarred and tell them i'm not addicted to him and even say "eww" or "yuck" but the truth is i think im obsessed. I think i have problems. Wanna cure it soon. Why do i have to have a bieber fever? damn.
