What do you call someone who thinks a certain person or people are constantly trying to degrade them when those people are not and it's not paranoia?

Such a person may be described as having a victim mentality or displaying a defensive attribution style. They may perceive themselves as being targeted or undermined without any actual intent from others. This mindset can stem from past experiences or internal insecurities rather than paranoia. It's often a reflection of their emotional state rather than an accurate assessment of others' intentions.
