Tracy,

I highly recommend this book- http://www.oup.com/us/catalog/genera...=9780195313048

Also look at the proposed DSM-V criteria for functional neurological disorder.

This will possibly help you understand the dangerous black hole in the border of neurology and psychiatry that I was referring to.

I am not saying that anxiety or fear or depression or sadness should not be properly recognized or that patients suffering from them should not receive proper support. On the contrary, even if they are a completely normal reaction to a devastating illness they are still real and lead to suffering.
