I'm schizoaffective and I only started to experience that complete loss of interest in arts three years ago. Movies had stopped encapsulating me when I first got ill ten years ago but books still moved me as they involved more applying of oneself, more intense concentration plus I was on a mission at the same time to write my own book. You could try and write your own story??

Back to music. You maybe need to look for a new genre. I never ever thought I would get into heavy metal but here I am an avid follower of the metalcore genre. Its so fast paced and rich in lyrical content. Try music that has lyrics??
