I've done EMDR on a number of occasions. With my first EMDR T I left feeling worse and wasn't able to function for a few days after. She was very caring and would let me stop when I felt overwhelmed. She didn't push me. She also didn't leave enough time at then end to help me come back to the present.

I've since learned she was causing more harm and was one of the reasons I lost it and ended up 30 days inpatient with ECT.

My current pdoc does EMDR very differently. She was taught by the woman who discovered/developed it. If I want to stop she will tell me we can, but I won't get through it. She encourages me without pushing me. I'm usually able to completely process my goal and have enough time to return to the present. If I don't get through it we continue it to the next session which is just a few days later, but she also always brings me back to the present.

And she makes herself available to me outside of sessions.

Talk to your T. Let her know everything that is happening. Find out if there is a different way to do this. Is she there to help you though these feelings?
