Start with the little picture; what is happening right now, right this instance. Right now/"this" instance is that you are afraid of being re-traumatized by reading this response to your post, by "me" and what I have to say. I might say something that will trigger you to be reminded of your trauma and you will feel those horrible feelings again.

The big picture for that is that you have been in this situation where you were afraid of being re-traumatized 8,204,685 times and only been seriously re-traumatized as a result, 5 times (I'm making up numbers here, obviously), so, the chances of you being re-traumatized that way are only 1 in 1,640,937. Since the odds are that good; you might be able to get yourself to risk reading this response without cringing as you do so?

The big picture is all the stuff you know about a situation, not just the part where you are focused on what you are afraid of in that situation. It's reminding yourself that there is a "more" to the story, not just the fear. It is realizing that if you are re-traumatized, you have been re-traumatized 5 times before and lived through it; it felt horrible but you survived.

Think about "this" situation, you have to look at where you are (on PC) and who you are reading ("me") and what you know about the site and its re-traumatizing you and about Me, Perna, and if reading my posts usually scares you or not, how you have felt in the past about situations like this one, not like the traumatizing one. It's shifting your perspective from the trauma to the "not trauma" and from the "this" to the "in general"/overall/bigger picture of your experiences throughout all of you life.
