Everything that stems from the brain is physical... er I sound like a hippy better go to an example or metaphor or something.
Real life scenario -- Some people are prone to seizures and "physical" docs don't really like to touch anything they dont understand. (not that they dont constantly but hypocracy is everywhere)
In most cases this person is refered to a neurologist/psychiatrist. Almost everyone I know on seizure medication recieves it from a psych.
My real life example: Since was about 8 yrs old I would literally start to get chest pains and have to just sit wherever I was (im not callin time out lol) and if I was 'got' so be it; better than that pain. Now I get to be about 12 and im waiting for the state spelling bee to start. This same pain returns. (It had quite a bit). I had been communicating this with my parents since the first time it had happened.
Thankfully my dad was a dr. of psychology and nailed in three questions. Does this usually happen around large groups of people? "Yes, unless I am alone and questioning how I am to get home." Do you ever get these pains when you are just goofing around, playing nintendo etc. "No".
So it is only when you are taking something very seriously and feel some kind of obligation to; friends, family, teachers, parents etc. "Yes exactly!"
Boy you got panic attacks, Im gunna get you into a psychologist. Which became a psychiatrist as life became harder and more stressful. By 17 it was well diagnosed that I suffer from panic attacks. If I had a regular GP could I convince him to do that; depends completely on ALL of the variables. But IMO/E No
