You're in your car, headed to the store.
Your boss asks if they can see you for a moment and then asks you to close the door.
You hear a raised voice from outside.
Suddenly, you're panicking. Maybe you feel terrified; maybe you're in tears. The anxiety is overwhelming. All you can think about is "Why is this happening?" and "I can't let anyone see how freaked out I am."
Everyone goes through trauma in their lives but for some people, that experience gets "stuck" in their brain. Instead of processing the event and moving on, the brain reacts to a seemingly harmless event by triggering the "fight, flight or freeze" reflex.
But just as therapies like ECT and TMS are showing remarkable abilities to help people with treatment-resistant depression, EMDR (eye movement desensitization and reprocessing) therapy is doing the same for people with forms of post-traumatic stress disorder.
