Confused please help

Ok in the beging of school I was a prep a little after school I was non prep but still pretty girlie than towards the end I was punk. Over this summer I have become total punk but now I like a little of the gothic style, but then also I like the tight jeans like preps do everyone tells me that if I dont find out what I am than I am a poser and I KNOW that I am definately not a poser what ever I say I can do.

It gets me SO FRIGGIN PISSED though I ask what do I say if they asked me what I am and I say I dont know and then of course they got somethin bitchy to say like hahaha ur a poser I even though I might not show it I get all pissed and depressed. And I just wanted to ask everyone one else is it a poser if you dont know wut u r in a style?
