Personality disorders are more fluid than most people give them credit for.

Yeah it seems to be that way, they’re like branches, some are born, and others end up treading into difficult spaces. It seems to me like whenever I discover the components of certain dysfunctions, I start expressing them in small quantities, it doesn’t usually leave my mind, but it’s very strange, maybe I’m just trying to get a better idea of the conditions by dabbling in them, but since it isn’t a deliberate choice, there may be something inherent that compels this behavior. 
Could decompartmentalisation be a cause?
