Q&A What are Scientific Psychological Side Effects from this sort of Marital Betrayal?

Hi John and Leslie, As I near the end of my HH group I feel like I am still grasping at sanity and mental health. I was wondering if you could explain to what extent such massive deception and such an excruciating disclosure (trickled out over time, pretend recovery, and gaslighting to the extreme) has on a partner's mental health. I feel as though I am in constant panic mode, that I may have a heart attack at any second, and that I can't get a grasp on what is real and what is not real. Anytime I feel safe I can sense my mind and body swing into hyperactive protection mode because I don't believe it. "Feeling safe" must mean that something is wrong. Having a "normal day" must mean I am being deceived. I feel like I am LOSING MY MIND. I guess what I really want to know is what are the true scientific psychological effects of this? Mind and body. Thanks.
