After war, a sudden sound or a familiar place can raise a difficult question: is danger present again, or is something bringing back what happened before? You do not need to tell your story in detail or prove that your reaction is justified before beginning. This article separates known circumstances, a possible threat, and your present experience. Actual protection comes first; nothing here asks you to test your courage by approaching danger. You can read only the sections about past and present, or move to the practical section. If observing yourself becomes difficult, you may stop. You do not have to feel calm immediately to use available support and choose a manageable next step.
