It is also quite common to feel tearful and cry in therapy, often much sooner than anticipated. You might feel surprised by the intensity of feelings but it is completely normal especially after having to hold so much, usually for quite some time. The tears might be as much about relief as about expressing sadness. There are boxes of tissues in the therapy room and I am very used to witnessing tears in the therapy room.
We aren’t very good at dealing with tears in this society. Because of this we can tend to be very self-conscious about crying in front of others. Please be reassured that I am perfectly comfortable with your tears and that all of your emotions are welcome. I don’t judge you for getting upset, actually I usually see it as a sign of progress!
