There are some good online tests to diagnose narcissism, psychopathy, sociopathy etc.
Kurwa, I almost forgot.
All this talk about mental disorders reminded me of the last session I had with my therapist. We have been working on some issues for quite a while now: personal interactions, empathy, anger management - that kinda f*cking useless sh*t (but my wife insists that I continue *rolls eyes*). To cut the long story short, this useless c*nt of a therapist claims that this board has a bad influence on me and that it effectively ruins her work (doesn't stop her from taking my money though!). So, I suppose I'll be taking a temporary break from PF but I'll definitely be back, b*tches.
