What I can't do

Before you begin to cry, here's a tissue. Wipe the tears from your eyes my baby, don't be afraid to show that pretty smile. My mind says you won't be here for a while but my heart is wanting you to stick around.  
 
I put my feelings up for auction, why don't you come and place a bid on them ? I ain't the same kid, please don't compare me to him.  
 
With the duel pistols in hand, why dont you pull the trigger right now? So you care enough not to gun me down?
 
I can take the bullet just don't break me down.
Dont break me.
My heart has had enough.  
 
Happiness is something tough to achieve.  
Too tough to achieve.
I am strong but some days I am weak.
 
Which part do you expect from me?
