I happened to find myself to have similiar thoughts and reactions in the book CONFESSIONS OF A SOCIOPATH, so I decided to take a online personality test. I know I am not naturally a sociopath but I do share some core characters like always wanna control others, really aggressive, lack of empathy, unforgiving of insults,(the part in book where Ms Thomas follows that janitor?? because he says something unpleasant or in an unpleasant tone echos strongly with myself). I plan on hostile revenge against others in a selective manner. Only those who I perceive to be threatening and malicious without object justification. I feign my charm too in order to function like a normal person but sometimes it is just so tiring and I just want to strip away all my fake smiles and stare at people with dead eyes (too). This kind of disorder might run in family because my uncle is a diagnsed psychopath and is on medication the whole life. My grandma ,when she was alive, had periodic peaks of hysteria.
I feel safe to confess here as it is paranoids' nature to think that any honest confession to others may be turned against them in the end.
The finding of the test proved to be extreme paranoid personality disorder. I am just happy that I find the source of my interpersonal difficulties . At some point reading the description of the result I felt paranoid personality disorder maybe sociopath taken to an extreme. not only do i feel lack of concerns of feelings of others, I interprete what they do as threatening and always on guard to take actions.
