Lost, alone and cold

You told me you loved me, I told you that too,
The only difference was what i said was true.

I'm living for you though you've made me feel dead,
The sun doesnt shine and there's rain on my bed.

I love you so much yet i hate what you've done,
My heart was the target and you were the gun.

My smile isnt real, im lost in the past,
I cant face tomorrow, how long will this last?

I'm an unfinished puzzle, coz one piece is gone,
You are that piece, with no other puzzle you belong.
