Dangerous new disease identified by person who, strictly speaking, isn't a medical professional

Have you got Taylor Swift Syndrome?

A doctor* explains:

Specifically, the singer said she's been drawing more from her own personal tales of love and heartbreak. "I have the Taylor Swift syndrome," she said, laughing. "I write off my own experiences."

* Not, actually, a doctor, but Vali, actually.

Like "restless leg syndrome", I'm not entirely sure this is a condition as such, given that 'writing from your own experiences' is what people are generally told to do when they write, isn't it?
