Iâm no expert in this, but do you use a brain stack?
Arenât BPD and schizophrenia due to chemical (and some other) imbalances in the brain?
Maybe try to research the physical causes and the numerous fields we have and how they would interact.
Also, the Thyroid field helps with mood changes for bipolar people, it probably helps stabilize moods to a degree for people with BPD as well.
