Rest your attention in the middle of your chest, let your breath slow as though it were moving in and out through there, and bring to mind something you feel warmly about.

You can tell you are back when there is choice in it again: you can pick which thought to keep hold of, and how to answer what you feel.

Sound sensitivity is not a fault in your hearing. Under threat the ear opens out towards high and low sounds, the range that carries warning, and that is the range which makes ordinary life feel loud.

If you went blank or floppy while something terrible was happening, that was your body conserving you. It is the oldest survival setting you have, not a failure of nerve.
