Sometimes earlier on in my therapy, before my therapists had learned all my quirks, I certainly managed to do that, but it didn't take too long before they had that aspect of me figured out and called me on any attempt to do so pretty quickly. I got to a place where I made the choice to just cut to the chase and let them know exactly "where" I was because I was ready to feel better and try to be done with all things therapy. The way my last therapist and I worked that out was that every session started with a routine of checking in on basic levels such as depression levels, sleep patterns, eating, etc.; we had taken the time to really define to how those related to and were indicative of my general well-being. It was important since I was dealing with bipolar symptoms; it was a way of keeping me honest with myself and with my therapist for my own safety and stability.
