Terrible Day.......

I'm trying to use Spaces to blog something useful. But I failed. I've terrible mood today & I'll write something depressed here.
I've tried to finish my Physics Experiment Reports until I realized that I even hadn't fulfilled Mathematics yet, to make things worse, I've stucked by an unexpected problem 4 nearly 2 hrs..I don't know,why,everything, everybody, & every stuff I met was trying to stop me from...well,I even don't know what the hell exactly it is...
