I don't know much at all about neurofeedback, but I do know about trust and how hard it is to trust again after being deceived or used. I'm sorry you were used in that. Happens too often! Many churches offer free counseling so you know they aren't doing it for money. I do know taking magnesium helps a lot to calm the mind body and spirit and gets rid of anxiety. Also ginseng is good to get rid of loopy negative thoughts. We can get in a serious loop of mistrust and it can really take us down. We need to trust some and I always say I can trust God to look out for me even when I am not sure I can trust the person. Let go of all of that fear since it is disabling, and remember the majority of people are good, as good as we can humanly be anyway. <3
