I had the whole damn world 
I watched it shatter underneath my feet
Now I'm lost in the underbelly of who I used to be
What do I have left when the hurt is gone

You were always my better half
I let my insecurities take you away
I tried to tell you how I felt but it would never come out right
Firefly I wish I got to open up before you left

Am not giving up on you 
I'm just growing numb to the touch
I'm no space cowboy 
I'm just a loser who couldn't keep the girl he loved

You were the medicine my depression feared
I have no used to this life of mine now
I'm growing ever cold again
Firefly why did you have to go away?

I wish I was a good enough reason for you to stay
But I know I'll never be
I love you so much but everything I love leaves
I just want your voice to always echo in my room
