You are clinically insane to some degree. You suffer from some form of mental illness that cause severe issues for you. The exact medical term is up to you. The greater the value of the trait, the worse the illness. It can be from mild paranoia to full on Dissociative Identity Disorder. The value of the trait should reflect how much of a disability it is for you personally, even if it's treated or medicated.
This trait is going to be reworked, or scrapped, pending sensitivity edits.
