Feeling so dumb....

I feel so bad and so dumb...
​I was aiming for straight As because this is the last time i could get them and last report card i got 9/11 As the others Bs.
​This time i got 10/11 As and am feeling so dumb and useless, i feel like i blow it and its the end of the world...  
​The worst part is, i failed the easiest subject it the damn world... Art.  I mean, what kind of a damn dumb ass fails art.  I dont know what i was trying to achieve i just feel so fricken dumb, i blew it!
