Promises I Can't Keep

What's the difference between a man and a monster
 Is it somewhere between "I can" and "I want to"
 Is it somewhere between the promises I made
 And the fact I couldn't see something getting in the way
 I used to think that I know what I want
 Never saw it coming unglued
 I used to think that I know what I want
 Now it's time to see if it's true
 I had so much certainty
 Til that moment I lost control
 And I've tried but it never was up to me
 I've got no worse enemy
 Than the fear of what's still unknown
 And the time's come to realize there will be

 What's the difference between a loss and a forfeit
 I tried to make it better, but I made it more sick
 I tried to make it right, now awake at night
 I know reality was getting in the way
 I used to think that I knew who I was
 Never saw it coming unglued
 I used to think that I knew who I was
 Now it's time to see if it's true
 I had so much certainty
 Til that moment I lost control
 And I've tried but it never was up to me
 I've got no worse enemy
