Be very careful about seeking help, sushi. Not every psychiatrist has their patients' best interests at heart and claiming and/or being diagnosed with certain symptoms could be grounds for involuntary institutionalization, which causes all sorts of problems even if you manage to get back out.

How do you know?
I'm curious because I might be getting there as well. Do you get any visual/auditory hallucinations?
