I don't think that's how somatoform disorder works.
How does it work, exactly? Such a mysterious disorder for which there is no test. Yet somehow more believable than mitochondrial disease? Says who? BCH?
In addition her numerous symptoms appear to fit those of mitochondrial disease. Yet I am supposed to believe BCH was able to rule out mitochondrial disease she was treated for over a year, in a couple of days?
