I have had it a couple of times. I just wasn't in the space to talk anything deep so when T asked her typical question like how are the kids and hubby, how is work (my job can be very triggering and stressful) I would talk about a lot of things like how the kids are doing in school, frustration with work, the mental health system ect. I would even ask T about her children, etc. I would essentially fill my session that way. When I got home I always felt upset that I wasted my time and there were things that I really needed to bring up.
