Her heartbeat and breathing are both accelerated. Too fast, ready for her to fight or flee, but there’s nothing there to either with. It’s the voices in her head, the past and the dangerous possibilities of the future. Nothing she can fight or change tonight, nothing that not being able to sleep will help, but try telling that to mistaken and abused impulses. It’s time to distract herself. Throw on a favorite movie. Pretend that she shouldn’t be able to use biofeedback to control the physiological response. Maybe it’s time to start a new project instead. Anything but the panic.
