Analysis of You're my nightmare

Thought ud be my everything
You said you'd love me for me
In one day everything changes
U played me how could I
Be so so blind
Never saw it coming
You and your friends bullied me
You could have made things right
But you chose to not
You are my nightmare
Sometimes I see your face
It's haunting me
Sometimes I feel we were meant to be
But you had to let me go
You gave up on us
You are My nightmare
You've hurt others like me
How can you walk around
With your head up high and smile and laugh
About all that you've done to me and others
You've hurt us for fun
You are my nightmare
I gave myself all to you
Loved you like no other
I was honest kind and true
But you chose to hurt me so
You are my nightmare
Forevermore
