I did EMDR and the calm place was my kitchen watching the humming birds at the feeder but visualizing the calm place when completely triggered does not work for me neither does their dumb containment exercise either.

What until you get to that one. You have to visualize placing the extreme feelings you have in a container, seal it, and put it somewhere that it can not escape. I had such a hard time even doing that so he made me think of a supportive person cheering me on to put it in and bury it. Nope sorry no supportive person in my life ever cheered me on. So he said I had to make up a fictional person or a super hero. So I said Ripley from Aliens. I could visualize all I want shoving nothing in a box or whatever but it never changed the extreme emotions I was feeling. I think just like voodoo you have to actually believe it is real to work and I just feel so silly every time i have to do that.
