Head problems

Why cant i get you out of my head?
why is it when i ever hear a word
it reminds me of you?
why is it when ever i hear a song
it gets me thinking of you?
i don't know why your doing this to me
your getting annoying
I'm getting ticked off
but yet i still think about you a lot
and i don't know why
so all i can say is:
GET THE HELL OUT OF MY HEAD
