I agree with @toomanycats. I find your compulsion to tell your T about your behavior to be interesting. I wonder what you are trying to accomplish. I understand feeling guilty, but telling her seems rather self-serving, like you are trying to force increased intimacy by revealing what you know - because then she has to react. I think you're getting something out of revealing your behavior and what you learned to her, not just out of the Google-stalking itself. I think you tell her to try to make her feel closer to you, and to distinguish yourself among her clients as "in the know." I don't think guilt is the primary motivator at all - because telling her doesn't benefit her in any way, only you. I think your behavior is intended to make her feel and be vulnerable to you.
