For a person dealing with trust issues, this sort of realization shatters any chance of progress, at least in my personal experience.
I can't feel safe if I think I could say the wrong word and have the cops drag me off for questioning. That's why I never got anywhere with counseling. For a person with trust issues, it's extremely important that you feel safe in counseling since you're making yourself extremely vulnerable by exposing yourself to them.
I've since dealt with a lot of my issues on my own. I haven't hurt myself intentionally in over two years, and that was an anomaly. It had been over two years since I had last hurt myself at that point.
The point is that these aren't easy problems, and there are no easy solutions.
