I would never wish my past on even my worst enemies. IT told me she was never abused that she could remember. I honestly think it would be harder for me if she did. I would fear triggering her. I know she had a very difficult relationship with her mom and she cut contact. It changed since or the things after my mom's death as I feared it would be hard for her.
I have no idea if Emdr T experienced anything like this.
As far as a menal heath diagnosis they haven't really said but I know T went to counseling after her divorce. Not sure about Emdr T but I am pretty sure she has a lot of anxiety. Having this types of struggles do help me as I k ow they undertand.
