I've lost the thought around this part:
> For example, consider a person who says, “now I understand why I have such negative thoughts, can’t get to sleep, and have difficulty getting going…I’ve got depression.” This person might believe that the explanation of her symptoms is depression, but in fact, the diagnosis of depression is just a categorisation of exactly these symptoms.
The diagnosis of depression usually revolves around changes in body chemistry and the functioning of the brain. It is an issue as real as diabetes is. To explain my point further, consider the following:
> For example, consider a person who says, “now I understand why I have such frequent urination, increased thirst and increased appetite. I’ve got diabetes.” This person might believe that the explanation of her symptoms is diabetes, but in fact, the diagnosis of diabetes is just a categorisation of exactly these symptoms. There is no diabetes Gremlin, either.
All this not to say that the accusations of fraud are either based or baseless.
EDIT: I know we can't test (blood etc.) for depression — yet. There's still a question of whether "it's all in your head" or "your biology is a bit off". See also [0].
