Uh, I've trawled through Wikipedia for the causes, and symptoms, of mental illnesses, and, according to my doctors (general practitioner, and psychiatrist), I've been good at identifying what I'm experiencing before I've gone to see them about it. The default case is that patients just go to the doctor, report their symptoms, answer questions about their lifestyle lately, and the doctors take care of diagnoses, and/or assigning treatment. I choose to believe that I have such clarity about my own mental processes because my doctors tell me how impressed they are when I come to them seeming to already know what I'm experiencing. I don't know why this is, but my lazy hypothesis is chalking it up to me being smart (people I know tell me this more than I would expect), and that I've become more self-reflective after having attended a CFAR workshop.

Of course, both my doctors, and I, could be prone to confirmation bias, which would be a scary result. Anyway, I've had a similar experience of observing my own behavior, realizing it's abnormal, and being proactive about seeking medical attention. Still, for everyone, diagnosing yourself by trawling Wikipedia, or WebMD, seems a classic example of an exercise prone to confirmation bias (e.g., experiencing something like medical student's disease). This post is a signal that I've qualified my concerns through past experience, and that I encourage you to both seek out a psychiatrist, as I don't expect that to result in a false negative diagnosis, and also to still be careful as you think about this stuff.
