Somatic Symptom Disorder, sometimes called Psychosomatic Disorder, is defined in the DSM V and does not mean the symptoms are "all in your head". It refers to patients with a compulsive-to-the-point-of-self-damaging focus on their condition, even if that condition is a diagnosed medical condition.

In other words, it's not a blank check to ignore these people.

To emphasize this, even if somatic symptoms are rooted in mental/emotional state, they’re still real and experienced as real.

I used to think it was real

Big elaborate stories in newspapers and magazines

It's like a professional disinformation campaign run by ??? to convince ??? to ???.

And it was absurd the whole time I guess

But I'm still not convinced that anything is real here except growing evidence of an extremely compliant mass media
