Not just your body. If you happen to be mentally outlying on the bell curve, you're going to be getting less than optimum care. I combine being an outlier on the intellectual side ("academically gifted and talented" was the terminology they used while I was in school) with being an outlier on the mental illness side (chronic depression, comorbid anxiety issues). The combination of the two means I've never yet run across a GP who's been willing to actually listen to what I'm saying rather than what their textbook appears to be dictating for me.

End result? I don't bother the GPs unless there's an actual physical problem to be treated, like a cold or flu. Otherwise, it really isn't worth the hassle.
