. I sometimes think if I had a set day/time each week, I would have had a sort of Pavlovian response to that day/time just out of habit. (Yes, I'm using that metaphor very loosely and a bit tongue-in-cheek). I would have perhaps felt possessive of that day/time; It's MINE!! Yadda yadda. This way I've never had that kind of association with any particular day/time equalling therapy. Instead, I arrange my therapy around other aspects of my life.

Perhaps you could try a compromise: maybe set your sessions about 10 days apart-ish. It will create a little more distance between sessions but not a full two weeks and perhaps not having a "set" day and time will help you not fixate on your session schedule as much. Might be worth a try.
