It's what people have when they are obsessed with and compulsively insist on playing the victim and keep on bragging that they have haters that keep on hating and abusing them. The said haters can be questionable as they could be based on their own imaginations.
That Eden singer sure has a chronic Imaginary Haters Syndrome. She's still gonna use it as her personality even if she might have future appearances in Eurovision, overshadowing her "talent" and sportsmanship and respect among her fellow artists. Can be connected to having delusions.
