'When my psychiatrist referred me to see you, she told me that you were a very good listener. I hold that opinion too and hope that you would stick to that trait of yours for the next few minutes.

I was thinking about cancelling this appointment but then I decided against it because I wanted to say goodbye. I do not think we have a strong connection and I think you would agree that I have not made much progress.
I have a few confessions to make. I have recorded a few of our sessions without asking you. I would understand if you do not believe me when I say this, I have deleted them. I feel bad about this but I checked your profiles on Facebook and Linkedin.

I wanted to give you some feedback to you regarding our sessions, which I think was the critical factor which made me want to attend this session.' Then I tell her that she is an excellent listener and I am extremely grateful to her for charging me for half an hour while giving me an hour (this arrangement started after I had attended 17 sessions, and I have been on a sliding scale for the past 4 sessions), and helped me through a tough phase in my life when I first started to see her. Then I mention some obvious areas for her to work are: 1) Punctuality: she is regularly late for the sessions (5-15 mins). Not so obvious: I felt abandoned when she did not reach out or check on me while I was having a really tough time in September when I had resigned from my job in August and was serving my notice period. (In her defense, I did not schedule any appointments for a month). She did not suggest that I should see her while I scheduled a session every two months. (Again, I understand that this was my decision it has nothing to do with her). And I tell her that scheduling appointments is difficult as she does not reply to messages timely (usually 1-3 days) and do not reply to emails.

Should I tell her this? Or should I just tell that I want to terminate and go over the key takeaways from our sessions?
PS. If I just cancel the session she might call my mom, and I do not want that.
