here in New York this is an inherited medical disease of the blood where they produce too much of the blood chemical kryptopyrrole. though it does have some mental symptoms like depression, psychosis, anxiety, and sometimes anti depressents and anti psychotics can help with those mental symptoms, here where I live and work it is treated as a medical problem by medical doctors. along with treating the depression, psychosis symptoms treatment includes mega doses of vitamins, zinc and B6.

if you think you may have this a simple routine blood test by your medical doctor can diagnose it.
