I've been seeing my T since October and he has never canceled. I canceled once the day of the session due to snow. We have had a couple of interruptions. He had a hard time making space for me in the schedule at first, so there was a gap of a month between our first and second session. We each took the same week off over Christmas, and I took a week off last month for vacation. But I don't consider these cancellations.

With my first counselor, she cancelled only once. In fact, she never even showed up because she was involved in a car accident. She was extremely apologetic about that, but heck, she was hit by a car and injured, so it's not like it was avoidable. With this counselor, I canceled many times with her or called to reschedule. I was really, really bad and had a hard time committing to therapy with her.
