It sounds like this T is being too leading and directive. I would be annoyed too. If what she says doesn't fit, can you say, "no, that's not it at all, this is how it is"?

I have done EMDR several times and I would not like it if someone tapped on me either. It would drive me nuts. We did it with these little electronic gizmos that pulsed. I put one in each shoe. T never touched me at all. He said I could put them under my thighs or in the shoes. I find the alternating pulses quite soothing. Do not let your T touch you if you are uncomfortable with it or annoyed by it. She should know that!

Maybe the EMDR would be helpful, but sounds like you need a different practitioner.
