If you've tried EMDR how did it help you?

So far I've tried EFT and instead of calming/turning down my emotions it activated me and that T recommended I go see a trauma therapist.

So far I've had two appointments with the new T and she has talked to me about trauma and has taught me some grounding techniques for me to practice before we do EMDR. I'm nervous that EMDR will activate me like EFT.

Any thoughts?
