I have realized later that I lied, because I was downplaying something in my head then realized it was a bigger deal than I thought. Or I have said "I don't know", when asked if what was bothering me if it was jumbled in my head or something I am not comfortable talking about. Overall I have been very upfront with my psychiatrist, though. I have been trying to say I am not comfortable discussing something if I am not, because it isn't like you should feel forced to give them information, but I also want to keep that honesty between us.
