I am currently in EMDR with a different T than my regular one. You should be sure your EMDR T has been certified to perform this therapy. Some Ts do it without the cert. From what you describe it sounds like she isn't.

As the tapping is happening there's no communicating. Before we start we pick the "target" belief. A certain points we stop and she asks me what comes up. I tell her and then continue. After we finish we go through some imagery and breathing exercises.

As Perna recommended, I would look for another EMDR T and I would further suggest that you meet with that person before signing on to find out more about them and their approach.

Good Luck
