I would focus at the candida and perhaps other parasites. I can honestly say that I have not seen any person so far who has only metal problems, but no candida and other pathogens. Candida is known to cause a multitude of mental problems, moodiness, mental laziness and at worst even hallucinations and panic attacks.
Treating your problem with zinc and molybdenum is not going to take you far, even if it is Andy Cutler that suggests it. I have not heard of anyone getting well on such a treatment alone, but you'll have ask Andy about that.

On the other hand I would suggest you try ALA, because it is a multi-purpose agent that bites on many things. A bad reaction to it confirms you have a problem that responds to treatment. I would also try an anti-candida diet for a few weeks and see if you get die-off reactions.
