I have an obsession problem?

Idk why but i have this weird obsession problem. I get completely obsessed with something and thats all i think about for a while--and i ALWAYS daydream about it. In the past, ive been obsessed with Evanescence, Suite LIfe of Zack and Cody, Zac Efron, Harry Potter, and more, But then, after like a week or two, i get over it and get obsessed with a completely different thing. Its really weird. BUt the weirdest thing is tht i like to obsessed with something and i cant reallly stand not having an obsession. Sometimes i even force myself to get obsessed with a tv show or book--mainly, i think, so that i have something to daydream about and something to wish for and something to think about when im bored. am i crazy or do other people also think like this?
