I can tell you what post-traumatic stress disorder is. It is the intense feelings of anguish you experience after a terrible experience. Say having your entire life stolen from you. When the WT figures out what to do to help, it will be too late, because they won't exist anymore.
Why do you hurt yourself? I can tell you. It's because you are taught that everything is a sin and that God is so personal he is right inside your head all the time, no wonder you are extremely introverted and introspective and lack any social ability to create or maintain meaningful relationships outside the cult so you cut yourself.
