When there are no more emotions for the artist

Most artists seem to be hyper sensitive.Not many are prepared for fame.
I was 16 when Kurt Cobain decided to join the 27 club. At the time an avid listener of his music, I still remember that day.
I recently came across his suicidal letter and found that it could be good TOK material. Whether his death was prompted by drugs, or depression is not for me to say, but the read gives us an insight into an artist who hasn't felt "the excitement of listening to as well as creating music along with reading and writing for too many years now."
