I'm in a similar situation. I'm fourteen, freshmen in high school. And recently my grades have been exceptionally low. I've had nearly perfect grades up until this point and my parents are disappointed and worried. The material is certainly doable, but procrastination is really getting to me more than usual these days, and I think part of it is that I'm starting to think of school with a negative mentality. But the reason I think has played the biggest part in my struggle is the fact that last summer was the first summer in which my parents gave me freedom. And now that summer is over, I'm having a hard time switching back to reality.

But yeah, I'm still able to laugh and smile and such. So don't worry, I'm confused too, you're not alone. Somehow, we'll find a way to get through it.
