Hi (((Teen Idle)))
There are a few websites that you could visit. I strongly recommend About.com Smoking Cessation, and ZaynQuit (that one is mine, hehe).
You'll feel much better, and healthier. Yes, we all have to die of something, sooner or later. But when we all get sick, smoking -even if it's not the cause- won't help.
And a magical tip for the cravings: think of them like something good, a sign of recovery!
I wish you the best!
Hugs,
Alex
