Trust is a hope that allows a person to be vulnerable with a professional without any fear of judgment. One feels safe to freely & respectfully communicate. Look back and introspect whether it is one off an incident or a regular occurrence which has affected you. If in case whatever transpired is an absolute non-negotiable for you, it is very difficult to fix, but if you are willing to put in sincere efforts to work around, talk about it, express and confront your feelings, it might help to overcome that disrupted the dynamics of life journey.
