Definitely tell her. You will feel better for it in the long run and it will only benefit your therapy. I don’t think new Ts expect us to be 100% honest right off the bat - we’re scared and nervous, but you can start to build that trust by being honest. I remember when I started with my T he told me I had 24 hours to come clean with anything because after that there was just no way to work with the info. I took advantage of that 24 hour option a couple times and then decided it was just easier to come clean right off the bat.

Having said that, I am in a bit of a situation with him right now and tried to explain what happened when I saw him last Sunday. I left out a critical part (I was scared). I sent him a text yesterday telling him there’s more to the story and I’d rather he hear it from me than someone else. He wrote me back and said it’s ok - he’s got the situation under control. I was terrified to send the text but really didn’t want to fracture his trust in me.
