Help with trauma
One of the simplest and most effective ways to help a person who has their attention fixed on something unpleasant, such as an accident or disaster, is the Locational Assist.
I've used it many times to help people in such a condition and it never fails. Just a couple of weeks ago I helped a guy who was having a panic attack. It took about 30 minutes but at the end of the assist the attack had gone and he was bright and smiling.
