Why can’t you be happy? 
Why do you delight in others' misery? 
You can’t be happy for your friends? 
You can’t stand it when they are happy? 

The pain of regret will come to bite you. 
You will lose out and others will move on. 
The cut will deepen as the time passes. 
It will gnaw away at you until there is nothing left. 

Your flesh will rot away as maggots eat you alive.  
It will fester and scab over, leaving you as horrid as you are now. 
Opening again at each new sting. 

The sting of pain and regret will eat at you, 
gnawing away the new skin and devouring you whole. 

The life of one with no happiness and the life of one who is not happy for others. 
Is an empty, useless, decrepit life.
