I hate it. Have gone back and forth and all around on this, both as a sufferer and someone who has spent over 30 years working in healthcare. My main frustration is the horribly fragmented way we approach health and illness. While it's great we've developed expertise in many fields, the downside is that we've chopped the body up to fit our evolving medical model.
The body is a unified whole so it seems absolutely absurd that we have created arbitrary divisions along physical vs mental lines. And where do those lines begin and end?? Many specialties deal with brain disorders, neurologists, neurosurgeons etc, so who decided which disorders psychiatrists handle and which ones others do?
My body does not know about or align itself with a hospital's organizational chart. It is a complex, integrated physical body system. If I am ill or injured my entire body is affected in one way or another by this. To cut my care and treatment up to meet the convenience of a created medical model is absurd and crazy-making.
And don't get me started on the term "behavioral healthcare"! That one actually triggers me because I find it so condescending and paternalistic. Who gets to decide what is or isn't appropriate behavior for another adult? Think about it, really think about it.
