Love & pain

I feel so empty yet so full
So dark yet so light
It makes everything dull
Turns everyday life into a fight
These feelings of nought
These feelings of pain
Created by my own thought
Wherein I can truly find no gain
From where they sprout I do not know
But they burn as a star
On the sky of my heart
I don't get it, it's all so bizarre
So believe me when I say sorry
Sorry for all the things I do
FOr I am still lost in your eyes, o so starry
You are not anymore the one I woo

But why makes this feel me so jealous then ?
