All is a weapon

I see red
My blood is boiling and it shows
And all you are is a weapon
You shoot 'em down 'til you end up alone
I seem fine
But I can't take the highs and the lows
All I am is a weapon
I shoot 'em down 'til I end up alone
I always say I hate the way you look at me now
And I swear I didn't mean to be a let down
What I broke can't be fixed with
All my sorry excuses, no
