EMDR stands for Eye Movement Desensitization and Reprocessing. It's a type of therapy that can help people feel less upset when they think about bad things that have happened to them. In EMDR, your therapist will help you recall a bad event, then have you move your eyes from side to side while thinking about it. This back and forth eye movement helps your brain make sense of the bad memory and helps you feel calmer when you think about it.
