Has she had extraterrestrial abductions or service in the Secret Space Program, and if so, what happened and how does it relate to her mental health issues?

This we have largely answered, that the latter are a recapitulation of the former—her service in the Secret Space Program paving the way for her to be manipulated while under orders to do violent acts on command. These were seen as symptoms of psychosis and she was thereafter treated as a mental patient and has been on antipsychotic medication for 15 years as a consequence of this medical assessment. It is understandable, but still, it is regrettable that the mainstream medical establishment fails to recognize spirit possession as a proximal cause of mental illness in the majority of cases. So their treatments are largely a stopgap and will never be able to cure things but only cover up symptoms. As you coached her, the distortion of the mind to create self-tormenting hallucinations is the hallmark of long-term spirit possession, as they work to create this self-induced attack to spare them the trouble. It is a sport for them to see what they can get the host to do to themselves.
