I had a therapist try EMDR on me even though she was not properly trained. I found it very triggering - of course, because you bring up the emotions! Plus it felt idiotic to have her fingers wiggling in front of me foolishly. EMDR and EFT (tapping) are pseudoscience. Of course it's good if the therapist can support you as you bring up emotions, and if some physical distraction helps in some way, that might help sometimes I suppose. For me, the only bright spot and sensible part is of these therapies is the affirmations. An affirmation such as "Even though I have . . . . . I fully and profoundly accept myself" is a valuable concept to embrace. Quite valuable, I'd say, in our very rejecting and judging culture!
