If you have a long term bacterial infection, you could be deficient of adequate copper levels. It's more likely that you are deficient of tyrosine and your melanin production is not as high as it has been. Your diet is the key to getting tyrosine and if you are low on tyrosine, you would think you would have trouble with the BH4 pathway and have issues like depression, insomnia, mood swings, etc.
