My therapist told me that I don’t lie (make things up that aren’t true). She said that I lie by omission. I don’t talk about important things because of my shame. I don’t talk about things that truly occurred because I fear the emotions that will surface.
She attended the wedding and simply responded “It was beautiful.” She told a lie by omission when she did not mention that there were many unpleasant occurrences.
