I have no doubt it's a woman who made it. Their understanding of the interpersonal dynamics of a codependent pair of people where one has a serious cluster B personality disorder is incredibly accurate. They either have the disorder, or they have a sibling with it. No one except someone in the mental health profession or someone who has actually had lived experience as/with a cluster B personality disorder could get it 100% correct down to the details. I honestly don't think I've seen a written example of a cluster B personality disorder depicted so accurately outside of a clinical text.
