Hi there Mona
Consistency is extremely important to me in my therapy . I go to my session the same day at the same time each week. That's not to say I'm not flexible, I am. Sometimes I have trainings or something work/ personal related or my therapist may have to cancel a session ( she always does this at least two weeks in advance). But otherwise we meet at the same time/day. It would be anxiety producing for me if we had to change the time and day around each week. I am pretty much the same way outside of therapy but I'm flexible within reason.
