In response to Anne 2.0:

Firstly, I told this T in the initial phone conversation that I need an after hours appointment as I work full time. She said she had those times available (which she does to an extent). After my first session which was on a Tuesday she asked if I wanted to book another appointment and would next Wednesday suit me. I asked her then if I could see her on Tuesday because I want to have the same day and time. She said other clients had those slots so I now I have to fit in between them. I said that was fine. There were no “guesses”. I was clear on my what I wanted. We then booked in a few appointments in advance and I assumed that would be my schedule moving forward. Turns out that is not the case and T only booked two weeks ahead then gave my appointment time to someone else.

I don’t know what kind of therapy you do but in psychoanalysis this is not how it is done nor has it been my experience in the past.
