Sometimes I wrote pretty long notes to T. She asked me to email them so she could read it ahead of time and process it.

With Emdr t. I make notes that I read just before I go into my appointment. There was one letter I wrote. It was a couple of pages typed. She asked if I wanted to read it to her out loud. I asked her to read it to herself and then we could discuss.she did and she started to respond after the paragraph. I asked her to finish reading first. It worked really well and said I am welcome to do it anytime.

As for length I think if you bring it to your appointment it can be however long you want it to be since it is your appointment
