Colour Transformation

I'm always changing my mind
What to say about you,the words are difficult to find
First you're a saint then a sinner
First a loser then quite the winner

Sometimes I'm so angry with you
I keep taking steps back,haven't one clue
At times so upset
I listen to see,what I get

Why did you change your colours
More interesting no just duller
The old you is what people lack
Trying to move forward,But I keep looking back
