Just recently did this with my T. It wasn't a full journal, just a few pages, though. I was in a very difficult place, emotionally, all through July and August. I started writing down just brief daily observations of mood, thoughts, self care stuff in August. It wasn't more than a short paragraph each day. I had intended to show T at each week's session, but I couldn't do it at the time. I was too paranoid and anxious and too scared of making myself that vulnerable. After the med change and my mood leveling out, I felt like it was something I wanted to show with my T. I felt like maybe it would help her understand what I was going through and help her to help me spot when my mood started spiraling toward an extreme.

I was really terrified of her reading what I'd written, because I had some very personal stuff in there that I wouldn't normally share. In one section, I'd written about sui feelings, and how I reached out to T, but then told her I was fine and I really, really wasn't.

T read it, and we spent some time last session on it. After giving it to her, I really didn't feel the need to dissect it. I asked her what she thought, and if it was helpful. T gave me her observations, which were that she felt such compassion for me reading it, and that while none of it was exactly a surprise, the depth of my experience was striking. She said it helped her to understand my experience a bit more. And, she also said that she found it impressive that I was able to function as well as I did while experiencing all that.

At that point, I just didn't want to talk about it more and I didn't even know what to say, so we moved on to another topic.

I think what might be helpful is to ask yourself what you want to get out of having T read your journal, and then when you go to your next session, maybe start with that. It helped me to narrow the conversation by determining that I mostly just wanted to share what I'd written.
