nothing much

Why is everything so annoying all of a sudden?
Its as if a deluge of cold water has swept over me, knocking the breath out of me, leaving me numb with coldness. I feel nothing, as I roam these walls- nothing motivates me.
There is no reason to study, as nothing makes sense- its all nonsense, all chatter, but no substance.
The world feels cold- or may be that's because of the water. May be not. Who knows?
I feel restless, nervous and jittery. Time has no meaning as I sit staring endlessly into the chasm that the future is...empty. I can't seem to process anything. May be I will in a while, when the coldness leaves me...
