Sorry you're feeling like this. I've not really tried EFT and don't know that much about it , but many techniques have the principle of energy being held in the body and addressing this along with other aspects like cognition and situational. I did EMDR , but for all of them there is the question of pacing and pitching which if it goes too fast brings up too much too soon and can feel overwhelming and having feelings such as you are. Perhaps your T is a little out of her depth and experience with this , maybe she could consult on it. Have you told her how this is making you feel ?
