I have used EMDR for years with my counselor. It is to process trama (Like child abuse, rape, etc.). But it can also help you process things like shame or depression or help you process a difficult situation.
The counselor give you two small boxes that buzz back and fourth. It's supposed to help trigger the left and right brain paths or something. You will think of an image or an memory and just let your mind wander. After a few minutes the counselor will pause the boxes and you will talk about what the last thing you thought about was. then it will continue.
It is harmless & it works more efficiently than talking does.
