What is this ?

You pull me back in.
And I know I can't stop typing, whenever I start.
But I know it's true.
And somehow I know, I will never ever get somewhere if this doesn't disappear.
Those things that keep on hanging around somewhere in my mind.
But I don't know what to say anymore.
It's been like this.
And it's like there's no ending.
I don't understand.
I wish I understood.
What is this?
Who are you?
