In this episode, Hannah talks to Dr David McLaughlan. He has a distinctly prominent voice and is a trusted mental health source on social media. Trigger warning: they discuss the ‘4 P’s that contribute to the onset of a persistent low mood - including biological underpinnings of depression - and talk at length about the increased numbers of those suffering in low mood due to the pandemic, at what point low mood might become a pathology, and how to support someone you love that may be suffering.
