I have the key..

Why is it so hard for me...  
Just for once I wanna feel free...  
One day with an empty mind...  
No more tears that I have to hide...  
 
Within my heart I feel so sad...  
It drives me crazy inside my head...  
Nobody knows the real me...  
I know its because I don't want them to see...  
 
Eventough I feel so alone...  
Building my wall stone on stone...  
Not really interested in my one human been...  
But even so...I know...I have the key...
