i well here's the prob...

since i started 9th grade i have been having probs with the exams and stuff i only get bad grades and it doesn't seem to be better. i have lost the motivation i had, and i feel like if iSUCK. I really don't know whats up with me everyone even my friends tell me that i have to study a bit more and stuff...everything i can say is "damn i would like but if i take a book and study i get depressed without a reason" they're like "WTF?!" and i just say "i hope i could change"

well i tried to explain in the most clear way i could (English isn't my first language )
