Cleanse me

Got an obsession  
Tearing me apart  
Call it a sickness  
So close to my heart  
 
Cancel it if I could  
Don't think I haven't tried  
Always comes to find me
No matter where I hide
 
Blessed with a beautiful wife
And two wonderful boys
Only thing I wish to bring them
Is life of laughter and joy  
 
Disease drives a wedge
They don't recognize me
So they leave me alone
With my fake family  
 
On the brink of destruction  
Don't know if I'll pull through  
God take this burden  
Cleanse me anew
