What is your profession, if I may ask?
There are other disorders that can appear similarly to sociopathy, just like how many other disorders share traits. There's also the matter of context that could make some things appear as others, like a bipolar I once knew who was diagnosed with depression since, every time he was around his parents in his youth, he was depressed.
A bipolar with antidepressants is fucking scary shit.
I'm pretty much a crazy person magnet. I don't really understand it myself.
Even my ex-fiance was a borderline personality disorder case, an ex-girlfriend was a nymphomaniac, and my first crush who I "dated" when I was young (lol, at that age it's not really dating) turned out later in life to be a lesbian.
I've met a few people with panic disorders, people falsely prescribed pills out of lazy diagnoses and paranoia from the parents (from young age application, it fucked up their lives), a sadist with dissociative identity disorder, schizophrenia, and depression, a fellow algolagniac (the discussion became chronic one-upsmanship), met quite a few ADD and ADHD types, knew two narcoleptics, know someone who later in life became a foot fetishist, and plenty of others I'm not remembering immediately.
I know more abberant types than normal people. Maybe my own disorders passively attract other people.
