Thanks Jessica,
Deep inquiring is being done constantly. Although it doesn't help that in my condition I can barely plan today's activities.
So I've been experimenting still and finally I more or less managed to dissipate my brain fog and anxiety for a little while.
My experiment consisted in eating as much seafood as I could for a week.

I ate my fill of oysters every day, and added clams and some shrimp.
The first day I ate as much as I could. The second day I could barely get out of bed, and even after my brain didn't seem to do better, I just couldn't wake up as If I were coffee addicted and didn't have my morning cup. Added to this I had incredible hunger which eventually was only satisfied by eating my fill of seeds and nuts. This relaxed me, and my mind started to wake up. At night, my brain fog and anxiety dispelled.
Next day I was still feeling good, and kept going. Third and posterior days no improvement.
I've repeated this experiment and more or less the same thing happens. I'm unable to wake up the next day until I eat seeds and nuts, and then eventually I start feeling better.
So I guess I'm pretty sure I have pyroluria now. Since its the mix of high zinc foods with high b6 foods thats trigged relief in my symptoms.
I did experience benefits from taking zinc sups, but I don't think I got any from the b6 supps because I can only get the pyridoxine hydrochlorine, which only made me pee highlighter ink.
I just asked friends who are traveling the states for zinc picolinate and p5p so I can start experimenting. I don't think theres a single physician in Mexico which could help me with it, so I'll have to keep experimenting and hope I can make things better soon.
