I've had trouble telling my T some things too. Once, with my first T, I spent a whole session wanting to tell her one sentence. I tore a styrofoam cup into tiny pieces before I told her. She reacted calmly and compassionately. When my current T and I do IFS or EMDR she usually has me close my eyes. I agree with MUE that it works best for me when I have to say difficult things to my T. With my eyes closed I of course don't see her looking at me. It's so much easier to talk. Maybe you could try closing your eyes? When I have to tell my T something I'm embarrassed about, I ask her a few times (I tend to repeat myself when I'm anxious) if it's okay to tell her anything, and if anything is TMI, and if she's sure? She has always reassured me that it's all right to tell her anything, and that she is not going to judge me, no matter what I say. I also agree with the "just blurt it out" method, though that doesn't always work. I wanted to tell my T one sentence. This seems to happen a lot with me in therapy! I kept starting it but stopped each time. I kept telling her "I'm going to say it" but I couldn't for a while. Then I did. Afterwards I had to email her and ask if it was okay to tell her. She said "absolutely" or one of her other favorite positive words that she uses with me. Good luck to you. I'm sure your T will accept whatever you have to say.
