kessa,

Keep telling her all your thoughts, including about feeling frustrated when you can't find the words and being extremely exhausted after therapy. All these things are important too. All the things you've written here are important for her to know.

I still sometimes smile or laugh and say "I HAVE NO WORDS!!" lol. Telling her can sometimes help break the tension and it's okay to not have words. They will come, she reassures me. There's plenty of time.

Telling her lets her reassure you. In time the dissociating will happen less as you feel more like staying there than not staying there.

Does she know that you mostly 'talked' via letters to your former T? Let her know that if you haven't already.

The words will come. You're learning to do this verbally rather than in writing. You're learning and learning takes time and practice, just like you are doing.
