"Be yourself" they say.. Leading to dismay

What Am I To Write About When I Have Mixed Emotions..?  
Pain, Love, Anger And Much of Sadness  
All That I've Been Through, Plain Madness  
I Can't Be Sad For A Day or so?  
I Can't Be Angry For A Day or so?  
I Cant Breathe! Can I Just Do As I Please!  
You Want Me To Be Happy..  
When I Feel The Complete Opposite  
I Know You Care About Me  
But This Pain I feel, Just Let Me Be....
