I had a hard time with EMDR too! I felt like I wasn't doing it 'right' and was judgmental of the process. I was able to express a lot of body memories but it's the questions "What do you notice now?" And I feel like there has to be an answer, and sometimes there's just not.

I think the T likes to have a dialogue so they know where you are, your distress level, and what is going on inside you.

It's possible you were not ready for it yet.. like another poster said. You could try talking a bit about it before the EMDR? It could be making you feel pressured..
