To begin with, I understand your trust issues- I have them as well. I think your idea of having an email where she can read what you write is a good place to start, however I advise you to be careful because that can easily become a boundaries thing where more communication is being done outside of session than in person.

I am sorry that she didn't read them, however, many she is waiting for you to bring it up so you can talk about it. I think maybe she was assuming that you writing things down would just be a step in helping you get to the point where you can talk to her about it in person. Like writing it down can help you get the thoughts out, and now she is waiting for you to do something with those- either talking about it, or bringing the entries to session and reading them to her, or even just bringing them to session to have her read them. I think maybe she is waiting for some action on your side. Just a thought.

As for going to session, I would go in and just go about how you would normally begin a session. Then gradually bring up what happened. She is probably going to wait for you to initiate the conversation but no doubt she wants to talk about why you were upset. At that point, you can explain to her how you wanted her to read your entries and how you were disappointed and irritated with her for not doing so, and that will open up a civil conversation between you to. Ruptures are sometimes the most important things in therapy because you can really use those to grow and make your relationship even stronger than it was before.

Don't give up. I think that you are going to be able to find a way to mend the relationship with your t. Give it time
