Answer: Darian would likely be considered as a depiction of Borderline Personality Disorder. She immediately idealizes Nick, becoming emotionally attached to him, which leads to her wanting him all to herself and becoming jealous of his relationship with Amy. Nick's rejection of Darian's sexual feelings for him and his insistence that they be simple friends is what leads her to her feelings of wanting revenge, while she also has unpredictable short-lived mood swings and unreasonable anger over trivial situations. To top it off, her pettiness and lack of remorse in sabotaging Nick in ways like vandalizing his car, erasing his work, trying to harm Amy and even her closest friend, would be almost certain to lead to a comorbid diagnosis of Antisocial Personality Disorder, especially considering she didn't change in the end, and those with BPD aren't typically violent against others (as media often portrays).
