Been there and done that too. If you consider avoiding questions,being vague, redirecting, and deliberately misintrepreting as indirect lying...then I kind of still lie occasionally.

I do not mean to diminish the theraputic relationship or the seriousness of the offense...but...I don't think it really matters much to our T's if we lie. What matters is what it does to US. A lie or slight distortion of the truth gives our ego (thinking brain) great stuff to torture us with between sessions. We are only hurting ourselves when we lie.

From my experience I recommend one of two things. You either contact your T and confess that you lied about X and tell him/her that you'll do your best to be more honest in the future. This will ease your guilt, disarm your ego a little bit to live more comfortably until your next session.

Or you look at yourself in the mirror, admit to yourself that you lied and commit to trying to be more open with your T on that topic. Even if being more open just means that the next time the topic comes up, you simply tell your T, "Last time you asked me about X, I wasn't really honest with you." Then you can either tell the truth or say, "I don't want to lie again, I'm not ready to go there." In this option you've at least admitted to yourself that you lied and you can work throught it yourself until next session.

IMO, the person you are "required" to be honest with is YOURSELF. Having said that, being honest with your T, although difficult at times, makes your overall therapy A LOT easier on yourself.
