Refika, the fact that it is bothering you means that it is in the way. It might make it easier to deal with to reframe how you think about your disclosure. Does the "lie" reflect a deeper psychological truth for you? Did the disclosure fill a need in the moment, in the relationship, or a long-standing need in your life? Do you feel like the "lie" protected you from some feeling or thought? Did it express a fear?

If you can take guilt out of the equation and think in terms of what psychological purpose the "lie" served, you will feel more at ease bringing it up. If your T is normally competent, I think that's how he'd view it.

Hopeless, when your T spoke of taking something personally, I doubt she was thinking of this sort of situation. She would have to feel personally invested in a way that was greater than her professional concern for you psychologically to see the issue judgmentally. Is it possible this is in any way connected to your leaving therapy for awhile? Give telling her some more thought.
