Promise

It's about a person I love dearly, written when I thought he didn't love me back...

Promise me that you'll be back
And stay with me forever.
I can never forget you,
Never, my love, never.

Your thoughts fill my mind
With happiness and pleasure,
Yet at the same time, a kind
of emptiness I can measure.
They both are equal,
Both are same
But the latter haunts me all the time,
Whenever I remember your name
I'm trapped in a box like a helpless mime.

A box of despair
A box of hate
A box that traps my soul
A box that I loathe,
A feeling that I
can no longer control.

Promise me that you'll come back
The only love of mine
Promise that you'll stay with me
If you don't want me to die.
