Ok what should I do and how should I feel?

Ok, you see evry1 I am depressed right now....I should be happy because I am 14 and it's summer but I'm not. In school we have the state wide test ya know? and I failed in school but it's only the math , sadly I knew I was; but went to summer school and I failed again and please don't mean and say oh your stupid or something because I am sad about this, but I THINK I am a good student it was conspicuous to me that I was not the best in math after 5th grade but I have never failed before and my teachers tell me that I am an excellent student and all but I just really suck at math I have even tried studying for an hour, so I clicked off the spongebob turned off the lady sovereign and really got down to ot but I didn't understand it I have even had tutors help me it doesn't work...I am not worried about ping to 9th grade because my teachers awarded me the best student of evry1 and it is their decision if I p, I just know I am bright but in math I can't show it???
