I see this is your first post , so welcome to the forum and I hope you will benefit from and enjoy your time here. I would discuss this further with your T , as he seems happy that you said something it could be productive. Feeling relieved but confused is not necessarily a bad or negative thing if reflected on , as in we may not have been able to express anger or frustration in the past and have things still be OK. Hopefully processing will continue for you from this.
