Define me

All these decisions I’m making they’re not the greatest
 
Quite frankly I don’t care  
 
Whore, fast, easy;
 
Whatever  
 
Honestly, they can’t faze me  
 
I’m bounded by these walls, these chains around my heart
 
I gave you my all
 
For my all I gave to you  
 
You trapped me in this box  
 
What I can and what I cannot
 
So whore, fast, easy;
 
Whatever the case may be
 
You do not define me  
 
And you do not get a say in how I fix what you have severed
