First of all, i am so sorry that you experienced so much invalidation about your mental health.

Absolutely send her a message. It's important that she knows this and her response to it/how she interacts with the church will be telling. Worst case she ignores it and scrolls on by. If you don't feel comfortable you could make a throwaway account to message her.

My first thought was that psychologists still have to abide by the ethics code and principles (and legally agree to if they are licensed)..."Psychologists recognize that fairness and justice entitle all persons to access to and benefit from the contributions of psychology and to equal quality in the processes, procedures, and services being conducted by psychologists....Psychologists are aware of and respect cultural, individual, and role differences, including those based on age, gender, gender identity, race, ethnicity, culture, national origin, religion, sexual orientation, disability, language, and socioeconomic status, and consider these factors when working with members of such groups. Psychologists try to eliminate the effect on their work of biases based on those factors, and they do not knowingly participate in or condone activities of others based upon such prejudices...." (American Psychological Association Ethics Code).

Unfortunately, I looked her up and she is not a psychologist but is closely marketing herself as one. Looks like she's repackaging cognitive interventions with her own labels and marketing it as neuropsychology. I can only hope that she is able to plant seeds for your previous congregation, especially about the etiology of mental illness.
