You sound so mature in your perspective about relying on your own coping mechanisms. And you wrote in your original post that it's going "up and up" so I think this wasn't just a particularly good session, you are really making progress apparently and I believe your therapist knows that as well as you. So it doesn't mean that there will be a fallout session. Offering you support if you need it until the next session really sounds as if she trusts you a lot, values the progress you make but wants to reassure you that she is there, even though she knows you are good about keeping boundaries and on using what you learnt. I love how strong and confident you sound, that makes me smile :-)

Love,
