Personally, I have deep doubts about both tapping and EMDR. They seem a bit too much like waving a magic wand around to me. But who knows. There is some research that supports it, however I would suspect a placebo effect. I have several times gotten worse in therapy, much worse in fact. To me it generally seems to come down to the relationship...If I feel heard, if I am buying into the treatment approach, if I feel like the therapist likes me, if I feel like she has real competence, etc. Research has consistently shown that the relationship is an important component to therapy, perhaps the most important component. If you are feeling worse it isn't your fault. The treatment isn't working and it's time to try something else.
