IMHO
The major psychiatric diseases have strong genetic interlinks with substance abuse and disorders of pain such as migraine and “fibromyalgia” (whatever that is...)
A lot of people diagnosed with fibro actually have systemic candida instead. Usually food allergies people aren’t aware of that makes them sick. Chronic fatigue, migraines, swollen joints, vomiting, digestive problems, all at the Same time. Sucks!!
