HELP ME! I can't stop thinking about smoking!?

I need help! I never smoked a day in my life saying that I'm only 14 but still I keep getting breadstick and pretending there ciggarettes. I've seen the most gory stuff on ciggarettes and they freak me out and I go all weak but I keep thinking stuff like"I wonder what it will taste like" and lots others. I'm becoming obessed [spelt it wrong sorry]. I'm not really asking a question I just want to know what you guys think, please don't be to mean.
