Kindness is not a disease - you just don't expect or know how to play the games of insecure unkind people 

This book is based on the best fictional character I've ever read to bring together my own school experiences of bullying, isolation and the depths of where this can take you too. I was lucky I had the contrast of home to not go to the depths of self-harm or suicidal thoughts.
