If only I had known, the regret you had inside.
if only I had seen, the pain you tried to hide.
If only I had realized, that things werent just quite right.
if only I had looked, and seen the pain you alone could fight.

Maybe If I had done these things, you would still be here.
Now theres that I can do, but cry another tear.
If only I had been there, if only I had known,
this regret, it fills my heart, a pain that over time grows.
