who am i (exactly) ?

it's 11 pm, the usual time I get into bed.

but why, why today, I feel different.

it's 11:10pm, the usual time I fall asleep.

but why, why today I struggle to.

it's 11:30pm, I'm awake and thinking.

but what do I think about.

it's 11:31pm, I'm thinking about me.

but what part of me.

it's 11:34pm, I'm thinking about what I want to be in the future, my dreams, my aspirations.

but I don't really know what I want to do.

it's 11:40pm, I still haven't made up my mind but I know I'm going to have to, one day.

it's 11:43pm, I'm still awake and thinking of other things to think about.

but I have to sleep, I know it.

it's 11:45pm, who am I ? Am I nice ? Am I secretly evil ? Am I happy ? Do I like that boy ?

but I don't know. I know nothing about me.

Who exactly am I ?
