No my gut feeling is nothing about imbalances of signal substances. My gut feeling is pure mind control of the kind that the Church hearings from the seventies talks about. Meaning to put a person through pure hell over a long time to get a separation of consciousness and then abusing this coping mechanism to get the person to do something she otherwise might not do. The religious bs she is clinging on to is her ordinary consciousness trying to make sense of what happened and justify her actions and inability to remember her actions.
This is my opinion when observing her past actions and the way she internally handles the said actions and the consequences thereof.
