Rabbits are adorable, and they are great pets, but like everyone says, they are a TON of work. I'm speaking from my experience as a rabbit owner, they are huge pains in the butts, and mine doesn't have most of the problems that rabbits can have. Thankfully he doesn't go to the bathroom anywhere except his litter box, and the only thing he has chewed up is a phone charger and a pair of head phones, but still, he is a ton of work and requires a ton of attention, and a ton of money. Oh boy are they expensive. (Something I didn't really realize until recently.) Between the pellets, the veggies, and the litter, and all the other little toys you can't pass up on because you think your bunny will love it, just adds up. Honestly I'd wait until you were at least 16+(w/ a part time job) to get a bunny. But even then, school and work and a bunny is a LOT to handle for such a young person. I'd wait.
Rabbits are like a cat, dog, and a toddler all mixed up into one. They look like simple, easy to take care of animals, but they're very complex.
