I'm not sure if it makes a difference. I know when I had my meltdown, I physically saw black eyes in people around me. The psych dude that was working on my issue said he was leaning towards it being bi-polar but acknowledges a strong PTSD element. The catch if I understood it correctly was that I physically saw this, i.e. hallucinations. I've never had that experience again. I know I am highly sensitive to a bi-polar diagnosis so that makes me "hopeful" that it's PTSD issue instead.
