The Fault in Our Stars - John Green Why ?

I finished reading ( The Fault in Our Stars by John Green ) again for the 45213444688 time , that was 4 hours ago and i'm still crying , i don't know - do i like to torture myself , or am i just too stupid to stop ?
What i know is i'm a sucker for this book :'( :') :)
Very realistic , full of emotions and unbelievably beautiful .
Its without a doubt the best book in 2012
