Depression again?

Yesterday night ordered Domino's Pizza...deliver to my
house. 6 regular pizzas is for 12 people, at least that's what
the coupon said stated. But I can prove that it is wrong.
You know why? Because my family of 5 people can finish
all of it xP 1 regular sized pizza got 6 pieces and I ate an
astonishing 9 pieces in 20 minutes!! XDD usually I can't
eat that much but don't know why yesterday so hungry.
=/ hehe~ Anyway, it was a delicious meal though =D

Today is suppose to be a happy day for me. A happy and
memorable day~(due to some reason)
but everything is ruined when I got back my BM paper 2.
I totaled it and the marks is 73%!! WTH?!
2 more marks to get an A!! Oh man!! Depress again...
>.< Couldn't believe it but how also I have to accept it.
Life still must go on right? Haiz...no point regretting when
it's over.
