Rage, anger, love, hate, passion, sadness: is there truly any difference?

I was just another blip of a moment, a second of your time, you never truly cared but I always bothered to spend my time on you

Emotions, love, my roller-coaster of you
I thought you were worth the fall because it meant from there we could only go up
But then I discovered a new depth of darkness

Coward.
That is all you ever were and all you ever will be
and finally I see
your true colors.
